Procedure
A mixture of 208 mg of 3-cyclohexene-1-carbonyl chloride (prepared from 3-cyclohexene-1-carboxylic acid and thionyl chloride) and 145 mg of triethylamine in 3 ml of methylene chloride is added to a solution of 377 mg of 5-(4-aminobenzoyl)-6,11-dihydro-5H-dibenz[b,e]azepine in 7 ml of methylene chloride. The mixture is stirred for 18 hours, washed with water, 1N HCl, water, 1M NaHCO3 and brine then dried with Na2 SO4. The organic layer is passed through a short column of hydrous magnesium silicate and hexane added to the filtrate at the boil to give 340 mg of the desired product as a crystalline solid, m.p. 234°-236° C.
