Procedure

A mixture of 0.9 g of 10,11-dihydro-N,N-dimethyldibenz[b,f][1,4]oxazepine-2-sulfonamide and 0.55 g of 4-nitrobenzoyl chloride in 3 ml of pyridine is stirred for 7 hours. To the mixture is added 20 ml of 2N hydrochloric acid and the mixture is extracted with ethyl acetate. The extract is washed with 5 ml of 2N HCl and three times with 5 ml of 2N Na2CO3. The extract is dried (MgSO4) and filtered through a thin pad of hydrous magnesium silicate. The pad is washed with ethyl acetate and the filtrate concentrated to give 1.1 g of a yellow solid. Crystallization from dichloromethane-diisopropylether gives 0.62 g of crystals, m.p. 177°-178° C.
