To a solution of 8-methoxy-11-oxo-6,11- dihydrodibenz[b,e]azepine (150 mg) in N,N-dimethylaniline (1 ml) was added 4-nitrobenzoyl chloride (140 mg) at 110° C. The mixture was stirred for 1 hour at the same temperature and diluted with ethyl acetate. The solution was washed successively with diluted hydrochloric acid and brine. The organic phase was dried over magnesium sulfate, and evaporated in vacuo to give crude 8-methoxy -5-(4-nitrobenzoyl)-11-oxo-6,11-dihydrodibenz[b,e]azepine (240 mg).
