Procedure

A mixture of 6.4 g (22 mmol) of 8-chloro-1-(2-fluorophenyl)-3,4-dihydro-5H-2-benzazepin-5-one and 6.4 g (34 mmole) of m-chloroperbenzoic acid in 350 ml of methylene chloride was stirred at room temperature for 2 hr. The methylene chloride solution was washed with saturated aqueous sodium bicarbonate and water, dried over anhydrous sodium sulfate and concentrated at reduced pressure to give a yellow oil. The oil was crystallized from a mixture of ether and petroleum ether to give off-white prisms, mp 166°-168° C. Recrystallization from a mixture of ether and methylene chloride gave colorless prisms, mp 168°-170° C.
