Procedure

To a stirred solution of 2-ethyl-1-[1-(4-fluorobenzyl)-1H-1,2,4-triazol-5-yl]butan-1-ol (0.368 g, 1.32 mmol) in pyridine (15 mL) at 0° C. was added methanesulfonyl chloride (0.61 mL, 7.9 mmol) and the solution was slowly warmed to room temperature. The mixture was diluted with H2O, extracted twice with EtOAc and dried (MgSO4), filtered and concentrated in vacuo to give a yellow oil in quantitative yield.
