Procedure

A mixture of 366 mg of 2,3,5-trichlorobenzoyl chloride and 151 mg of triethylamine in 2 ml of methylene chloride is stirred while 314 mg of 5-(4-aminobenzoyl)-6,11-dihydro-5H-dibenz[b,e]azepine in 5 ml of methylene chloride is added. Stirring is continued for 1.5 hours. The reaction mixture is partitioned with water and the organic layer is washed with 1N HCl water, 0.5 N NaOH and brine. The organic layer is dried with Na2 SO4 and passed through a pad of hydrous magnesium silicate. Hexane is added to the filtrate at the boil to give 0.52 g of white solid residue which is purified by column chromatography on silica gel by elution with 2:1 hexane-ethyl acetate to give 120 mg of the desired product as a crystalline solid, m.p. 225°-230° C.
