实验过程

To 4-isopropyl-7-nitro-2,3,4,5-tetrahydro-1,4-benzoxazepine (17.46 g) in methanol (1.5 1) was added acetic acid (36 ml) and zinc dust (36 g) portionwise, and the mixture was stirred for 3 h. The mixture was diluted with water (1 1), basified with conc. ammonium hydroxide (250 ml), and extracted with ethyl acetate (5×250 ml). The extracts were dried with magnesium sulfate, filtered and concentrated to an oil (11.34 g, 74%) which was used immediately in the next step.
