3622-35-3, Benzo[d]thiazole-6-carboxylic acid is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
After adding benzothiazole-6-carboxylic acid (5.0 g, 27.9 mmol), HATU (15.9 g, 41.9 mmol) and DIPEA (11.7 mL, 83.7 mmol) to dichloromethane (87 mL) and N,N-dimethylformamide (22 mL), the result was stirred for 30 minutes. To the reaction solution, an N,O-dimethylhydroxylamine salt (3.0 g, 30.7 mmol) was introduced, and the result was stirred for 12 hours at room temperature. After terminating the reaction, the reaction solution was removed, and ethyl acetate was added thereto. The result was washed with water and saline, then dried using anhydrous magnesium sulfate, and filtered. The filtrate was concentrated and purified using column chromatography to obtain a target compound (6.2 g). 1H NMR spectrum (300 MHz, CDCl3) delta 9.13(s, 1H), 8.36(d, 1H), 8.16(d, 1H), 7.87(dd, 1H), 3.57(s, 3H), 3.42(s, 3H).
3622-35-3, 3622-35-3 Benzo[d]thiazole-6-carboxylic acid 601670, athiazole compound, is more and more widely used in various fields.
