実験手順

A solution of 2-p-nitrophenyl-4H,6H-1,3,4-oxadiazin-5-one (Example 17; 2.2 g.) in ethyl acetate (250 ml.) was hydrogenated in the presence of a 5% palladium-on-charcoal catalyst at laboratory temperature and atmospheric pressure until 670 ml. of hydrogen had been absorbed. The mixture was filtered and the filtrate was evaporated to dryness. There was thus obtained as solid residue 2-p-aminophenyl-4H,6H-1,3,4-oxadiazin-5-one, m.p. 253°-255° C. (with decomposition).
