Versuchsvorschrift

A mixture of methyl 3-formyl-5-nitrobenzoate (0.418 g, 2.0 mmol), hydroxylamine hydrochloride (0.209 g, 3.0 mmol) in ethanol (5.0 mL) was heated at reflux for 2 h. On cooling, the mixture was poured into water and the precipitate collected by filtration. The cake was recrystallized from ethyl acetate-hexane and dried to give 0.22 g (49%) of methyl 3-[(N-hydroxylimino)methyl]-5-nitrobenzoate as an off-white solid, mp 144°-145° C.
