Reaction Steps

To a solution of 16.4 g of 1,2,3,4,8,9-hexahydropyrido[4',3':2,3]indolo[1,7-ab][1]benzazepine in 500 ml. of dichloromethane, 7.3 g. of cyclopropanecarbonyl chloride was added, followed by dropwise addition of 10 ml. of triethylamine. A mildly exothermic reaction took place, after which stirring of the mixture was continued at room temperature overnight. The mixture was then washed with 1N hydrochloric acid and water and dried over anhydrous sodium carbonate. On evaporation to dryness, crude 3-(cyclopropylcarbonyl)-1,2,3,4,8,9-hexahydropyrido[4',3':2,3]indolo[1,7-ab][1]benzazepine was obtained as a glassy product. Recrystallization from ethanol yielded the pure material, m.p. 154°-156° C.
