Versuchsvorschrift
A solution of 4-naphthalen-2-ylmethyl-5-nitro-4H-benzo[1,4]oxazin-3-one, I-59 (0.65 g) in methanol (30 mL) and dioxane (7.0 mL) was hydrogenated in presence of 10% Pd—C at 45 psi for 22 h. Reaction mixture was filtered and the filtrate was concentrated to give 5-Amino-4-naphthalen-2-ylmethyl-4H-benzo[1,4]oxazin-3-one, I-60 (620 mg).
