Procedure

To a solution of 2-[5-(4-bromo-phenyl)-3-methyl-isoxazol-4-yl]-ethanol (0.100 g, 0.35 mmol) and triethylamine (0.10 mL, 0.71 mmol) in THF at 0° C. was added methanesulfonyl chloride (0.05 mL, 0.62 mmol) and the reaction stirred at 0° C. for 1 hour. The mixture was diluted with H2O and extracted with EtOAc, and the combined organic layers were washed with H2O, saturated aqueous NaHCO3, and brine. Dried over MgSO4, filtered, and concentrated to give the title compound.
