Reaction Steps
Following Example 91, to a solution of methyl 4-(8-bromo-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-3-chlorobenzoate in tetrahydrofuran and water was added lithium hydroxide, monohydrate to give 4-(8-bromo-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-3-chlorobenzoic acid, which was coupled with methylamine, HBTU, and DIEA in dichloromethane to give 8-bromo-N-(2-chloro-4-(methylcarbamoyl)phenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide.
