Procedure

A solution of 4-hydroxy-3-(2-nitrophenyl)-1,2,4-triazole (0.38 g, 1.8 mmol), prepared according H.G.O. Becker in J. Prakt. Chem., 1970, 312, 610, in 96% ethanol was hydrogenated over 5% palladium on charcoal at room temperature for 1 hour. The reaction was filtered through a pad of celite to give desired material on evaporation of the solvent.
