A mixture of 1.11 g of 5-(4-nitro-3-methyl-benzoyl)-6,11-dihydro-5H-dibenz[b,e]azepine, 50 ml of ethanol, 0.30 g of anhydrous hydrazine and 0.27 g palladium-on-carbon is refluxed 1 hour, and then filtered through diatomaceous earth. The filtrate is evaporated and the residue recrystallized from dichloromethane-hexane to give 0.80 g of crystals, m.p. 203°-204° C.
