Versuchsvorschrift
6-Nitro-2H-pyrido[3,2-b]-1,4-oxazin-3(4H)-one (1 g) was reduced under hydrogenolysis conditions using 10% Pd—C in methanol (50 mL) and 1N HCl solution (10 mL) at 50 psi for 2 h. The catalyst was filtered off and washed with methanol and 1N HCl solution. The filtrate was evaporated to give 6-amino-2H-pyrido[3,2-b]-1,4-oxazin-3(4H)-one.
