Procedure

To a solution of 385 mg of 2-chloro-benzoyl chloride in 6 ml of methylene chloride at 0° C. is added 0.6 g of 10-(4-aminobenzoyl)-10,11-dihydrodibenz[b,f]-[1,4]thiazepine followed by 0.375 ml of triethylamine. The reaction mixture is stirred at room temperature for 18 hours. The reaction mixture is washed with 20 ml of water, 1N HCl, 1N Na2CO3, water and dried over MgSO4. The filtrate is evaporated in vacuo to give 0.7 g of yellowish solid which is purified by silica gel chromatography on thick layer plates by elution with 1:1 ethyl acetate-hexane to give 0.3 g of the desired product, m.p. 116°-119° C.
