Procedure

To a solution of 4-(4-chlorophenyl)-3-(3-cyanophenyl)-2-butanol (1.0 kg, 3.5 mol) in toluene (10 L) at 0° C. was added triethylamine (684 mL, 4.9 mol) and methanesulfonyl chloride (353 mL, 4.6 mol). After stirring for 5 min, the reaction mixture was filtered, and the precipitate was washed with toluene (8 L). The filtrate was washed with sodium bicarbonate (6 L, 50% saturated aqueous solution) and water (3 L), and concentrated to give the title compound.
