Adding a certain compound to certain chemical reactions, such as: 641571-13-3, name is 3-(4-Methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)benzoic acid, belongs to imidazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 641571-13-3, Application In Synthesis of 3-(4-Methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)benzoic acid
(E)-7-(5-amino-2-methylstyryl)thieno[3,2-d]pyrimidine-4-amine (100 mg, 0.354 mmol) and 3-(4-methyl-1H-imidazole-1-yl)-5-(trifluoromethyl)benzoic acid (96 mg, 0.354 mmol) were dissolved in DMF (1.5 mL), HATU (404 mg, 1.063 mmol) and TEA (0.248 mL, 1.7728 mmol) were added thereto and stirred at room temperature for 18 hours. The reaction mixture was diluted with ethyl acetate and washed with brine. The organic layer was dried with MgSO4, filtered and concentrated. The resulting mixture was purified by silica gel chromatography to obtain the title compound (142 mg, 75% yield). MS m/z [M+1] 535.15.
