117724-63-7, 2-Methyl-4-(trifluoromethyl)thiazole-5-carboxylic acid is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: Under nitrogen atmosphere, carboxylic acid II (3mmol), EDCI (3.3 mmol), HOBT (3.3 mmol)and Et3N (1.8 mmol) were placed in a three-necked flask with 40 mL CH2Cl2, and stirred for 2 hat 0 C; then, compound I (2.4 mmol) was added to the flask and allowed to react for 3 h at 0 C.The reaction was monitored by thin-layer chromatography (TLC) (all reactions could be completed in3 h) and, on completion of the reaction, the mixture was washed with saturated NaHCO3 solutionand water, respectively. Then, it was dried over anhydrous Na2SO4, filtered and evaporated onrotavapor in vacuum. Subsequently, crude products III-1-III-18 were purified by silica gel columnchromatography [V (CH2Cl2): V (EA) = 3:1] and crude products III-19-III-36 were purified by silicagel column chromatography [V (PE): V (EA) = 3:1]. Finally, products were recrystallized with thedichloromethane/petroleum ether to obtain pure target compounds.
117724-63-7, As the paragraph descriping shows that 117724-63-7 is playing an increasingly important role.
