Procedure

To a stirring solution comprised of two(2) N-sec-butyl-2-(4-cyano-3-trifluoromethyl-phenoxy)-4-hydroxy-3,3-dimethyl-butyramide diastereomers (1.63 g; 4.38 mmol) in pyridine (10 mL) at 0° C. under a nitrogen atmosphere is added methanesulfonyl chloride (0.75 g; 6.5 mmol). The reaction mixture is stirred cold for 3.5 hours. The reaction mixture is diluted with dichloromethane and is washed with 1N aqueous hydrochloric acid and with brine. The organic phase is dried over anhydrous magnesium sulfate and is concentrated in vacuo (the water bath temperature is not raised above 23° C.) to afford 1.892 g of a foam; HPLC UV purity: 99.3% (two diastereomers.)
