Methanesulfonyl chloride (0.26 ml, 0.39 g, 3.4 mmol) was added dropwise to a stirred, cooled (-30° C.) solution of 3-(5-methyltetrazol-1-yl)-5-(trifluoromethyl)phenylmethanol (725 mg, 2.8 mmol) and triethylamine (0.59 ml, 0.43 g, 4.2 mmol) in dichloromethane (15 ml). The mixture was stirred at -30° C. for 45 minutes, diluted with dichloromethane (20 ml), washed with aqueous citric acid (10%, 20 ml) and saturated aqueous sodium hydrogen carbonate (20 ml), dried (MgSO4) and the solvent was evaporated under reduced pressure to give 1-(methanesulfonyloxymethyl)-3-(5-methyltetrazol-1-yl)-5-(trifluoromethyl)benzene as a yellow oil (877 mg, 93%), 1H (CDCl3) δ 7.86 (1H, s), 7.81 (2H, s), 5.38 (2H, s), 3.14 (3H, s), and 2.69 (3H, s).
