Procedure

To a solution of 5.0 g (0.029 m) of N-chloroacetyl-N-methylcarbamoyl chloride dissolved in 40 ml of toluene was added 4.74 g (0.029 m) of 2-methyl-2-methylsulfonylpropionaldoxime dissolved in 35 ml. of toluene followed by a slow addition of 2.9 g (0.029 m) of triethylamine. The reaction mixture was stirred at ambient temperatures over a period of 3 days. The solid product was filtered. The filter cake was washed with water and hexane and air dried to afford 5.7 g of a white solid with a melting point of 120°-121° C.
