Procedure
In five portions 0.5 g (7.9 mmol) of sodium cyanoborohydride and 35 ml of a 1 M methanol solution of methanesulfonic acid was added over 4 hr to a solution of 2.0 g (6.1 mmol) of 8-chloro-6-(2-chlorophenyl)-2H,4H-pyrrolo[3,4-d][2]benzazepine in 50 ml of methanol which was cooled to 0°. When the addition was complete stirring was continued overnight at room temperature. The solution was basified with 40% aqueous sodium hydroxide and diluted with water. The resulting precipitate was collected by filtration to give a white solid. Recrystallization from a mixture of ether and methylene chloride gave colorless crystals, mp 211°-212°.
