1-Chloro-3(1,2,3)triazol-1-ylpropan-2-ol (2.3 g, 13 mmol) was treated with the solution of NH3 in methanol (25% by weight, 20 mL) at 60° C. overnight in a sealed pressure vessel. After cooling to room temperature, nitrogen was bulbbed into the reaction mixture to remove the ammonia. Evaporation of solvent gave the hydrogen chloride salt of 1-amino-3-(1,2,3)triazol-1-ylpropan-2-ol (2.57 g, 100%). 1H NMR (DMSO-d6) δ2.68 (dd, J=8.8, 12.8 Hz, 1H), 2.97 (dd, J=3.6, 12.8 Hz, 1H), 4.15 (m, 1H), 4.44 (dd, J=6.4, 14 Hz, 1H), 4.57 (dd, J=4.6, 14 Hz, 1H), 5.95 (d, J=5.2 Hz, 1H, OH), 7.77 (s, 1H), 8.01 (brs., 3H, NH3+), 8.12 (s, 1H). MS (m/z) 143.1 (M+1).
