Reaction Conditions

Reaction Steps

To a four-necked flask having an inner volume of 500 ml and equipped with an electromagnetic stirring device, a nitrogen inlet tube, and a thermometer, there were charged 10.0 g (57.7 mmol) of 5-norbornene-2-sulfonamide, 15.1 g (180.0 mmol) of sodium bicarbonate, and 200 g of dichloromethane. After cooling the mixture to 5° C., 14.8 g (60.0 mmol) of 70% m-chloroperbenzoic acid was added thereto over a 20 minute period, and the mixture was stirred at 5° C. for 2 hours. To the reaction mixture was added 100 g of distilled water, and the mixture was separated into an organic layer and an aqueous layer. The organic layer was washed with 40 g of distilled water and concentrated under reduced pressure. By recrystallizing the residue obtained from ethyl acetate, there was obtained 6.89 g (36.4 mmol) of 5,6-epoxy-2-norbornanesulfonamide represented by the following formula (yield 63%):
