Procedure

A stirred solution of 2-(4-fluorophenyl)-2-hydroxyiminoacetonitrile (42.8 g, 0.26 mole) in 200 ml of pyridine was cooled to 0° C., and p-toluenesulfonyl chloride (76.0 g, 0.39 mole) was added portionwise. Upon complete addition, the reaction mixture was stirred at 0°-5° C. for one hour and then stored in a refrigerator for 16 hours. The resultant slurry was poured into a mixture of ice and water and stirred for 30 minutes. The mixture was then filtered and the white filter cake dried under vacuum without heat to give 2-(4-fluorophenyl)-2-(4-methylphenylsulfonyloxy)iminoacetonitrile (77.3 g, mp 129°-140° C.).
