Procedure
The N-(α,α-dimethylbenzyl)benzenesulfonamide used as a starting compound in the above procedure could be prepared in the following manner. A two-layered mixture consisting of 33.8 g (0.25 mole) of α,α-dimethylbenzylamine and 120 ml of a 10% aqueous solution of sodium hydroxide was stirred at below 40° C., and 44.1 g of benzenesulfonyl chloride was added dropwise. Stirring the mixture for an additional 1.5 hours afforded a white precipitate. The solid precipitate was collected by filtration, and recrystallized from methanol to afford N-(α,α-dimethylbenzyl)benzenesulfonamide having melting point of 114° to 115° C. in a yield of 67%.
