Reaction Steps

A solution of 1-(4-nitrophenyl)methyl-1,2,4-triazole (10.0 g, 49 mmol) in ethanol (50 ml), ethyl acetate (50 ml), 5N HCl (10 ml) and water (10 ml) was hydrogenated over 10% Pd/C (1.0 g) at 40 p.s.i., in a Parr apparatus, until an uptake of 188 p.s.i., had been observed (approx 10 mins). The catalyst was removed by filtration through hyflo and the solvent removed under vacuum. The residue was azeotroped with ethanol (×2) to give the titleamine hydrochloride (10.6 g, 100%). δ (360 MHz, D2O) 5.53 (2H, s, CH2), 7.37-7.48 (4H, m, Ar-H), 8.12 (1H, s, Ar-H), 8.66 (1H, s, Ar-H).
