Propargyl alcohol → (1-(4-methoxybenzyl)-1H-1,2,3-triazol-4-yl)methanol

Participants

Reaction Steps

93 mmol 1-(azidomethyl)-4-methoxybenzene, 110 mmol propargyl alcohol were mixed in 230 ml tert-butyl alcohol/H2O (1:1) solution. 1 mmol CuSO4.5H2O and 10 mmol Ascorbic acid sodium salts dissolved in 2 ml water were added into the solution. The mixture was stirred for 2 days. After evaporation, the mixture was purified by flash column to give 55 mmol (1-(4-methoxybenzyl)-1H-1,2,3-triazole-4-yl) methanol. 1H NMR (CDCl3): 7.42 (1H, s), 7.22 (2H, d, JH-H=8.70), 6.88 (2H, d, JH-H=8.70), 5.43 (2H, s), 4.73 (2H, s), 3.79 (3H, s).
