Reaction Steps
A solution of 3.0 ml (33 mmol) of phosphorous oxychloride in 20 ml of methylene chloride was added dropwise to a solution of 3.0 g (9.1 mmol) of 8-chloro-6-(2-chlorophenyl)-2H,4H-pyrrolo[3,4-d][2]benzazepine in 40 ml of dimethylformamide which was cooled to 0°. Stirring at 0° was continued for 2 hr. The mixture was poured into a saturated solution of aqueous sodium carbonate and extracted with methylene chloride. The methylene chloride solution was washed with water, dried over anhydrous sodium sulfate and concentrated at reduced pressure to dryness. Purification by column chromatography (silica gel, 100 g; eluent, 50% (v/v) ethyl acetate in methylene chloride) gave a light pink solid, mp 270°-274°. Recrystallization from a mixture of ethyl acetate and methylene chloride gave peach colored prisms, mp 276°-277°.
