35272-15-2, The synthetic route of 35272-15-2 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.35272-15-2,2-Methylthiazole-4-carboxylic acid,as a common compound, the synthetic route is as follows.

1.00 g (6.99 mmol) of 2-methyl-1,3-thiazole-4-carboxylic acid was added to 3.62 g of polyphosphoricacid. 0.64 g (6.99 mmol) of hydrazinecarbothioamide was added portionwise. It was stirred for 1 h at140 ¡ãC. After cooling down to 70 ¡ãC, water (10 mL) was added dropwise. After cooling to 0 ¡ãC,aqueous ammonium hydroxide solution (25percent, 8 mL) was added till a pH value of 12 was achieved. The precipitate was collected by filtration, washed with water and dried under reduced pressure at 50 ¡ãC affording 821 mg (59percent of theory) of the title compound.?H-NMR (400MHz, DMSO-d6): 6 [ppm]= 2.69 (s, 3H), 7.33 (s, 2H), 7.96 (s, 1H). LC-MS (Method 4): R = 0.65 mm; MS (ESIpos): m/z = 199 [M+H].

Downstream synthetic route of 35272-15-2

As the paragraph descriping shows that 35272-15-2 is playing an increasingly important role.

35272-15-2, 2-Methylthiazole-4-carboxylic acid is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General Procedure: To a 100 mL round bottom flask equipped with a stir bar were added 2- methyl-l,3-thiazole-4-carboxylic acid (1.0 g, 6.98 mmol), potassium carbonate (3.86 g, 27.9 mmol), N,N-dimethylformamide (20 mL) and iodomethane (0.52 mL 8.38 mmol). The reaction mixture was stirred at room temperature over the weekend, diluted with ethyl acetate (100 mL) and washed with water (100 mL). The aqueous layer was then extracted with ethyl acetate (3×75 mL). The combined organic layer was washed with brine (100 mL), dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was purified on silica gel using hexanes:ethyl acetate = 80:20 to 50:50 in a gradient fashion, to give the desired product as an off-white solid (1.06 g, 97 percent). 1H NMR (300 MHz, CDCl3): delta 8.06 (s, IH), 3.95 (s, 3H), 2.78 (s, 3H).

The solvent was reduced to ~40ml and the reaction mixture was applied across 5×70 g aminopropyl SPE cartridges and left to stand for 3h. The cartridges were eluted with DCM:methanol (1 :1 ) and the combined solvent was evaporated in vacuo. The residue was suspended in DCM:methanol, adsorbed onto Florisil.(R). and purified by chromatography on silica gel (10Og cartridge) eluting with 0 – 15percent gradient of methanol (containing 1percent triethylamine) in DCM over 60min to give title compound (1.02g).
