Reaction Steps

To a mixture of 3-(8-bromo-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-4-chlorobenzoic acid (3 g, 6.09 mmol) in THF (50 mL) was added EDCI (2.34 g, 12.18 mmol), HOBt (1.23 g, 9.13 mmol), DIPEA (5 mL) and 2-aminoethanol (0.56 g, 9.13 mmol) by sequence under nitrogen atmosphere at room temperature. The reaction mixture was stirred overnight, diluted with water. The resulting precipitate was washed with water and EtOAc to give 8-bromo-N-(2-chloro-5-(2-hydroxyethylcarbamoyl)phenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide (2.52 g, yield 77%). LC-MS: (ESI, m/z)=535 [M+H]+
