A mixture of 0.349 g of 2-chloro-5-(4-aminobenzoyl)-6,11-dihydro-5H-dibenz[b,e]azepine, 0.131 g of triethylamine and 0.201 g of 2-methylbenzoyl chloride in 13 ml of dichloromethane is stirred at room temperature for 3 hours. The mixture is poured into water and the organic layer separated. The organic layer is washed with 1N HCl, H2O, 1N NaHCO3, brine and dried (Na2 SO4). The solution is filtered through a thin pad of hydrous magnesium silicate and the pad washed with dichloromethane. The filtrate is concentrated and the solid crystallized from dichloromethane-hexane to give 0.32 g of crystals, m.p. 187°-189° C.
