Triethylamine → N-(2-(tert-butyldimethylsilyloxy)ethyl)-N-(2-chlorophenyl)-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide

Participants

Reaction Steps

To a solution of N-(2-(tert-butyldimethylsilyloxy)ethyl)-2-chloroaniline (0.145 g, 0.508 mmol) and triethylamine (0.113 mL, 0.812 mmol) in tetrahydrofuran (1 mL, 10 mmol) was added a solution of 4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carbonyl chloride (0.107 g, 0.406 mmol) in tetrahydrofuran (4 mL). The reaction was stirred overnight and concentrated in vacuo. Aqueous work up gave a yellow solid which was purified on silica by MPLC to give 150 mg of N-(2-(tert-butyldimethylsilyloxy)ethyl)-N-(2-chlorophenyl)-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide.
