2-(1H-1,2,4-Triazol-1-yl)benzonitrile (4.25 g, 25 mmol) was dissolved in ethanol (50 mL) and 1N HCl (25 mL). 10% Pd—C (1 g) was added and the mixture shaken under H2 for 2 h at 50 psi. After filtration through Celite® and concentration, the residue was triturated with diethyl ether and the title compound was collected as a white solid. (3.94 g, 75% yield). 1H-NMR (300 MHz, CD3OD) δ ppm: 9.01 (1H, s), 8.32 (1H, s), 7.78-7.64 (4H, m), 4.15 (2H, s). LCMS [M+H]+ calcd for C9H11N4: 175.09; found: 175.17.
