実験手順

To a solution of methyl 4-(N-(2-(tert-butyldimethylsilyloxy)ethyl)-10-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-3-chlorobenzoate (0.250 g, 0.436 mmol) in tetrahydrofuran (10.2 mL, 126 mmol) and water (10.2 mL, 566 mmol) was added lithium hydroxide, monohydrate (0.0732 g, 1.74 mmol). The reaction mixture was stirred at room temperature overnight. The reaction mixture was concentrated, acidified with 1M HCl, and extracted with DCM (3×). The combined organics were dried (Na2SO4), filtered and concentrated to give 4-(N-(2-(tert-butyldimethylsilyloxy)ethyl)-10-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-3-chlorobenzoic acid (yield 60%). MS: (ESI+) 559.1
