Preparation Example 26; 3-Phenylpropan-1-amine (11.33 g) and potassium carbonate (11.58 g) were added to acetonitrile (300 mL), and MeOH and a solution of ethyl 2-(bromomethyl)-1,3-thiazole-4-carboxylate (11.64 g) in acetonitrile (30 mL) in an ice bath were slowly added dropwise thereto, followed by stirring at room temperature for about 1 hour. To the reaction mixture was added an appropriate amount of ice water, followed by extraction with ethyl acetate several times. The organic layer was washed with brine and dried over MgSO4, and then the solvent was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate_hexane=3:1 to 5:1) to prepare ethyl 2-{[(3-phenylpropyl)amino]methyl}-1,3-thiazole-4-carboxylate (13.17 g).

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.78502-71-3,Ethyl 2-(bromomethyl)thiazole-4-carboxylate,as a common compound, the synthetic route is as follows.

78502-71-3, To a solution of ethyl2-(bromomethyl)-1,3-thiazole- 4-carboxylate (19, 2.4 g, 9.7 mmol) in toluene (20 mL) triphenylphosphine (2.7 g,10 mmol) was added at room temperature, and the resulting mixture was stirred at 100 C for 3 h. The reactionmixture was cooled to room temperature, and the precipitate was collected by filtration, washed with hexanes, anddried to afford ((4-(ethoxycarbonyl)-1,3-thiazol-2-yl)methyl)(triphenyl)phosphonium bromide (31, 3.7 g, 74%) as abrown powder, which was used without further purification. To a mixture of compound 30 (2.2 g, 5.5 mmol) andcompound 31 (3.7 g, 7.2 mmol) in N,N-dimethylformamide (20 mL) was added sodium ethoxide (0.75 g, 11 mmol)at room temperature, and the resulting mixture was stirred at room temperature for 3 h. The reaction mixture waspartitioned between ethyl acetate and water. The organic layer was separated, washed with brine, dried over MgSO4,and concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluting with a gradientof 10-50% ethyl acetate in hexanes) to afford the title compound 20a (1.8 g, 60%) as a pale yellow powder.

Brief introduction of 78502-71-3

As the paragraph descriping shows that 78502-71-3 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.78502-71-3,Ethyl 2-(bromomethyl)thiazole-4-carboxylate,as a common compound, the synthetic route is as follows.,78502-71-3

To a solution of 6-fluoro-5-methoxy-2-phenylindole (200 mg) in N,N-dimethylformamide (4.1 mL) was added sodium hydride (dispersed in liquid paraffin, minimum 55%, 54 mg) under cooling with ice, and the mixture was stirred at room temperature for 70 minutes. Then a solution of ethyl 2-bromomethylthiazole-4-carboxylate (249 mg) in N,N-dimethylformamide (0.2 mL) was added, and the mixture was stirred at 80 C. for 25 hours. The reaction mixture was allowed to cool to ambient temperature. A saturated aqueous ammonium chloride solution-water (2/1) were added to the reaction mixture and this resulting mixture was extracted with ethyl acetate. The organic layer was washed successively with water and saturated saline, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate-hexane) to obtain the title compound (125 mg).In addition, structural formula and spectrum data of the title compound are shown in Table 29

As the paragraph descriping shows that 78502-71-3 is playing an increasingly important role.

Simple exploration of 78502-71-3

The synthetic route of 78502-71-3 has been constantly updated, and we look forward to future research findings.

78502-71-3,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.78502-71-3,Ethyl 2-(bromomethyl)thiazole-4-carboxylate,as a common compound, the synthetic route is as follows.

Example 7; 2-{(3-phenyl-1H-indazol-1-yl)methyl}thiazole-4-carboxylic acidSodium hydride (added with 40% mineral oil, 9 mg, manufactured by Kanto Chemical Co., Inc.) was added to a solution of 3-phenyl-1H-indazole (40 mg), which had been synthesized according to the literature (T. Edward, C., et al., Tetrahedron, 1991, 47, 9599-9620), in N,N-dimethylformamide (1 mL, manufactured by Kanto Chemical Co., Inc.) under ice cooling, and the mixture was stirred for 5 minutes at the same temperature. Subsequently, ethyl 2-bromomethylthiazole-4-carboxylate (51 mg) synthesized according to the method of the literature (K. Benno, et al., Leibigs. Ann. Chem., 1981, 4, 623-632) was added thereto, and the mixture was stirred overnight at room temperature. Water (1 mL) was added to the reaction solution, and the mixture was extracted with ethyl acetate (3¡Á2 mL), washed with brine (10 mL), and dried (MgSO4). The solvent was then evaporated. The resulting residue was purified by PTLC (hexane:ethyl acetate=2:1), to give 7.2 mg of the title compound. LC-MS: HPLC retention time 4.08 minutes, m/z 336 (M+H), condition A-1.
