Procedure

130 ml of tetrahydrofuran was added to a mixture of 7.6 g of N-benzoyl-N-methylhydroxylamine and 6.3 g of vinylsulfonyl chloride and a solution of 5.1 g of triethylamine in 20 ml of tetrahydrofuran was dropwise added to the mixture over 2 hours with stirring while cooling the mixture so that the temperature was maintained at 25° C. or less. The reaction was continued for additional 2 hours at a temperature ranging from 15° to 25° C. and then the same procedures used in Preparation Example 4 were repeated to give 9.2 g of o-vinylsulfonyl-N-benzoyl-N-methylhydroxylamine.
