Pyridine → N-(1-Acetyl-8-chloro-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-N-(3,5-bis-trifluoromethyl-benzyl)-acetamide

Participants

Reaction Steps

Add acetyl chloride (0.3 mmol) followed by dimethylaminopyridine (cat.) and pyridine (0.3 mmol) to a solution of N-(3,5-Bis-trifluoromethyl-benzyl)-N-(8-chloro-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-acetamide (0.05 g, 0.11 mmol) in dichloromethane (1 ml). After stirring for 14-16 h dilute with dichloromethane (2 mL) and wash with 5% HCl (2 mL), water (2 mL) and brine (2 mL). Dry the organics over sodium sulfate, filter, and remove solvent under vacuum. Chromatograph the crude product over silica gel using ethyl acetate/hexane (10-30%) to elute. This afford the title compound (0.04 g, 89%) as a colorless solid: MS (ES+): 507 (M+H).
