Procedure
In one portion, 0.7 ml (6.2 mmol) of 30% hydrogen peroxide was added to a 1% solution of concentrated sulfuric acid in acetic acid. After stirring for 1 hour, 1.7 g (4.2 mmol) of 8-chloro-6-(2-chlorophenyl)-1-methyl-2H,4H-pyrrolo[3,4-d][2]benzazepine-2-acetamide were added, and the resulting solution was stirred for 30 minutes. The excess peracid was discharged by the addition of saturated aqueous sodium bisulfite solution, and the mixture was concentrated at reduced pressure. The residue was partitioned between methylene chloride and water and neutralized with concentrated ammonium hydroxide solution. The methylene chloride solution was washed with brine, dried over anhydrous sodium sulfate, and concentrated at reduced pressure. The residue was crystallized from ethyl acetate to give 8-chloro-6-(2-chlorophenyl)-1,4-dihydro-1-methyl-3-oxo-2H-pyrrolo[3,4-d][2]benzazepine-2-acetamide as colorless prisms, mp 221°-222° C.
