실험 절차

2-ethyl-4-nitro-1,3-benzoxazole is hydrogenated under a pressure of 8 bars in the presence of 10% palladium on carbon (0.01 eq.) using methanol as a solvent. The catalyst is separated by filtration and the methanol is eliminated under reduced pressure. The residue is taken up in ethyl ether in order to produce a pale violet solid which is collected by filtration and dried. Melting point: 46° C.
