実験手順

A mixture of methyl 3-[(N-hydroxylimino)methyl]-5-nitrobenzoate (2.0 g, 0.009 mol) in ethanol (150 mL) was hydrogenated in the presence of platinum oxide (0.25 g) at 30 psi for 0.5 h. The catalyst was removed by filtration through Celite and the filtrate was concentrated. The residue was recrystallized from ethyl acetate-hexane to give 1.1 g (64%) of methyl 3-amino-5-[(N-hydroxylimino)methyl]benzoate as an off-white solid, mp 160°-162° C.
