Procedure

1-[4-(4-Nitro-phenyl)-butyl]-1H-[1,2,3]triazole (2.89 g, 11.74 mmol) is hydrogenated in a mixture of methanol/THF (1:1, 50 ml) in the presence of palladium on charcoal (10%, 0.5 g) for 5 h. After filtration solvents are removed in vacuo yielding 4-(4-[1,2,3]triazol-1-yl-butyl)-phenylamine as a yellow gum. Yield 2.03 g (80%)
