Procedure

To a mixture of tert-butyl piperazine-1-carboxylate (1.7 g, 9.13 mmol), DIPEA (3 mL), HATU (2.78 g, 7.31 mmol) in THF (60 mL) was added 3-(8-bromo-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-4-chlorobenzoic acid (3.0 g, 6.09 mmol) under nitrogen atmosphere at room temperature. The reaction mixture was stirred overnight, diluted with water, extracted with EtOAc. The organic layer was dried over Na2SO4, concentrated in vacuo to give tert-butyl 4-(3-(8-bromo-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-4-chlorobenzoyl)piperazine-1-carboxylate (3.9 g, yield: 97%). LC-MS: (ESI, m/z)=682 [M+Na]+
