PROCEDURE
实验过程
A solution of 2-chlorothieno[3,2-b]pyrazine-6-carboxylic acid 23 (219 mg, 1.019 mmol), HATU (465 mg, 1.223 mmol) and DIPEA (0.337 mL, 2.039 mmol) in DMF (6 mL) was stirred for 15 min at rt. N-(3-amino-4-methylphenyl)-3-(trifluoromethyl)benzamide 67 (300 mg, 1.019 mmol) was added and stirred overnight at rt and overnight at 60° C. The reaction mixture was poured out in 3% citric acid solution and the resulting precipitate was collected and washed with water to give compound 2-chloro-N-(2-methyl-5-(3-(trifluoromethyl)benzamido)phenyl)thieno[2,3-b]pyrazine-6-carboxamide 68 (389 mg, 78%). (m/z)=491 (M+H)+.
