Procedure

Purge a mixture of isopropyl-5-[acetyl-(3,5-bistrifluoromethylbenzyl)amino]-7-bromo-2,3,4,5-tetrahydrobenzo[b]azepine-1-carboxylate (0.400 g, 0.672 mmol), trimethylboroxine (0.084 g, 0.672 mmol), and potassium carbonate (0.279 g, 2.02 mmol) in anhydrous tetrahydrofuran (5 mL) with nitrogen, then add tetrakis(triphenylphosphine)palladium (0) (0.077 g, 0.067 mmol) and stir at reflux for 1 h. Cool the mixture to room temperature and dilute with ethyl acetate (30 mL) and wash with water and brine (10 mL each). Dry the organic layer over anhydrous sodium sulfate, filter and remove the solvent under reduced pressure. Chromatograph the residue over silica gel, eluting with hexanes/ethyl acetate (20:1 to 3:1), to provide the title compound as a white solid (0.156 g, 44%): ESI MS 531 (M+H).
