With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.188937-16-8,2-(2-Thiazolyl)acetic Acid,as a common compound, the synthetic route is as follows.

To a solution of 5-bromo-4- (4-fluorophenyl) -6-hydrazinylpyrimidin-2-amine (400 mg, 1.3 mmol), 2- (1, 3-thiazol-2-yl) acetic acid (384 mg, 2.7 mmol), TEA (543 mg, 5.4 mmol) in DMSO (10 mL) was added HATU (1.3 g, 3.4 mmol). Stirred at 25C for 4 hours. The resulting mixture was poured into 100 mL water and filtered. The solid was dried in vacuum to afford N- [2-amino-5-bromo-6- (4-fluorophenyl) pyrimidin-4-yl]-2-(1, 3-thiazol-2-yl) acetohydrazide (336 mg, 59%) as a dark-grey solid. LCMS: m/z (ESI), [M+H] + = 423, 4. 1H NMR (300 MHz, DMSO-d 6) delta 4.05 (s, 2H), 6.42 (s, 2H), 7.28 (t, 2H), 7.54-7.70 (m, 3H), 7.75 (d, 1H), 8.75 (s, 1H), 10.22 (s, 1H)., 188937-16-8

The synthetic route of 188937-16-8 has been constantly updated, and we look forward to future research findings.

Intermediate 36A: N-(3-Bromo-2-methylphenyl)-2-(thiazol-2-yl)acetamide A mixture of 3-bromo-2-methylaniline (0.764 mL, 6.20 mmol), 1,3-thiazol-2-ylacetic acid (0.74 g, 5.17 mmol) and DIEA (1.63 mL, 9.30 mmol) in DMF (15 mL) was treated with HATU (2.36 g, 6.20 mmol). After stirring overnight, the mixture was diluted with EtOAc, washed twice with 10% aqueous LiCl followed by brine, and the combined aqueous layers were extracted with EtOAc. The combined organic layers were dried and concentrated, and the residue was purified by column chromatography on silica gel, eluting with EtOAc-hexanes, to give N-(3-bromo-2-methylphenyl)-2-(thiazol-2-yl)acetamide as a white solid (0.681 g, 42% yield). 1H NMR (400 MHz, chloroform-d) delta 9.84-9.65 (m, 1H), 7.91 (d, J=7.9 Hz, 1H), 7.84 (d, J=3.3 Hz, 1H), 7.42-7.35 (m, 2H), 7.07 (t, J=8.0 Hz, 1H), 4.18 (s, 2H), 2.38 (s, 3H).

188937-16-8, 188937-16-8 2-(2-Thiazolyl)acetic Acid 21220663, athiazole compound, is more and more widely used in various fields.
