Procedure
A catalytic amount of Raney nickel was added portionwise with stirring to a mixture of 2-[(4-nitrophenyl)methylene]-2H-1,4-benzoxazin-3(4H)-one (0.57 g, 0.002 mol) and hydrazine hydrate (1 ml) in ethanol (20 ml). The reaction mixture was refluxed for 3 h, then filtered. The filtrate was evaporated to dryness under reduced pressure. The crude product was purified by re crystallization from ethanol.
