Participants

Reaction Steps

Phosphorus pentachloride (0.3 g, 1.44 mmol) was added slowly to a solution of 1-(cyclopropylmethyl)-5-phenylazepan-2-one (0.35 g, 1.44 mmol) in dichloromethane (8 mL) at 0° C. After 1 h, iodine (3.6 mg, 0.01 mmol) and bromine (0.07 mL, 1.44 mmol) were added, and the mixture was allowed to warm to ambient temperature. After 1 h, another 0.3 g of phosphorus pentachloride was added. After an additional 18 h, the reaction was quenched with saturated sodium bicarbonate. The mixture was extracted with dichloromethane (3×), and the combined organic extracts were washed with water (3×), saturated brine, dried over sodium sulfate, filtered and concentrated.
