7305-71-7, 2-Amino-5-methylthiazole is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: To a stirred solution of -corresponding hetero amines a?e (0.04?mol) and triethyl amine (0.04?mol) in chloroform (200?ml) was added drop wise chloroacetyl chloride (0.04?mol) at 0?5?¡ãC. After addition, the resulting mixture was stirred overnight at room temperature. Reaction completion was monitored through thin layer chromatography using hexane:ethyl acetate (8:2) as mobile phase. The reaction mixture was concentrated to get solid and as such taken in the methanol solution. The precipitates thus separated out were allowed to stand 2?h. The resultant solid 1a?e was filtered, washed, dried and as such taken for the next step.

As the paragraph descriping shows that 7305-71-7 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.78485-37-7,Ethyl 2-chloro-6-benzothiazolecarboxylate,as a common compound, the synthetic route is as follows.

To ethyl 2-chlorobenzo[d]thiazole-6-carboxylate (1d-1) (305 mg, 1.263 mmol) and (1R,3R,5S)-N-((5-cyclopropyl-3-(2,6-dichlorophenyl)isoxazol-4-yl)methyl)-8-azabicyclo[3.2.1]octan-3-amine hydrochloride (1c-1) (430 mg, 0.842 mmol, ?84% by weight) in DMA (5 ml) was added cesium carbonate (686 mg, 2.105 mmol). The resulting mixture was heated up to 60 C. for 16 h, cooled down to room temperature. The mixture was diluted with ethyl acetate, washed with water (4*), brine, dried, filtered, and concentrated. The residue was chromatographed by CombiFlash eluting with hexane to 70% ethyl acetate/hexane to give ethyl 2-((1R,3R,5S)-3-(((5-cyclopropyl-3-(2,6-dichlorophenyl)isoxazol-4-yl)methyl)amino)-8-azabicyclo[3.2.1]octan-8-yl)benzo[d]thiazole-6-carboxylate (Example 1) (198 mg). LC/MS observed [M+H], 597.15.

173979-01-6, 4-(Tributylstannyl)thiazole is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

(R)-7-(4-bromo-lH-imidazol-l-yl)-5-cyclopentyl-4-ethyl-4,5-dihydro- [l,2,4]triazolo[4,3-f]pteridine (Example 93), 4-(tributylstannyl)thiazole (1 eq, seeExample 693) and Pd(PPli3)4 (0.1 eq) are dissolved in DMF in a screw cap vial and a stream of nitrogen is bubbled through the mixture for 2 minutes. The vial is sealed and the resulting solution is stirred at 100 C for 19 h. The reaction mixture is diluted with brine, extracted with EtOAc, dried with Na2S04 then purified by flash chromatography with a silica gel column by eluting with a mixture of Hexane:EtOAc and then further purified by preparative HPLC to give the title compound.

The synthetic route of 173979-01-6 has been constantly updated, and we look forward to future research findings.

494769-44-7, tert-Butyl (4-(hydroxymethyl)thiazol-2-yl)carbamate is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

tert-Butyl 4-(hydroxymethyl)thiazol-2-ylcarbamate (2.0 g, 8.68 mmol) was taken up in 25 mL of CH2Cl2 along with Et3N (1.82 mL, 13.05 mmol) and cooled to 0 C. Methanesulfonyl chloride (0.85 mL, 10.88 mmol) was added and the resulting reaction mixture was stirred at 0 C for 60 min. Morpholine (3.0 mL, 35 mmol) was then added and the reaction mixture was stirred at room temp for 18 h. The reaction mixture was concentrated under reduced pressure. The resulting residue was taken up in EtOAc and washed with dilute aqueous NaHCO3, brine, dried with Na2SO4, and concentrated under reduced pressure. This material was purified by filtering through a short column of silica gel. The filtrate was concentrated to afford tert-butyl 4-(morpholinomethyl)thiazol-2-ylcarbamate (1.88 g, 69 % yield).

494769-44-7 tert-Butyl (4-(hydroxymethyl)thiazol-2-yl)carbamate 22280475, athiazole compound, is more and more widely used in various.
