PROCEDURE
实验过程
A solution of 2-oxo-1,2-dihydrothieno[3,2-b]pyrazine-6-carboxylic acid 84 (27 mg, 0.138 mmol), TBTU (48.6 mg, 0.151 mmol) and DIPEA (0.068 mL, 0.413 mmol) in DMF (1 mL) was stirred for 15 min. N-(3-amino-4-methylphenyl)-3-(2-cyanopropan-2-yl)benzamide hydrochloride 6 (45.4 mg, 0.138 mmol) in DMF (1 mL) was added and stirred overnight at 50° C. Quenched with water and extracted with EtOAc. Organic layer was washed with water, dried and evaporated. Purification by HPLC gave the title compound N-(5-(3-(2-cyanopropan-2-yl)benzamido)-2-methylphenyl)-2-oxo-1,2-dihydrothieno[2,3-b]pyrazine-6-carboxamide 85 (0.2 mg, 0.308%). (m/z)=472 (M+H)+.
