実験手順: 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%. could be prepared in the following manner Stirring the mixture for an additional 1.5 hours afforded a white precipitate The solid precipitate was collected by filtration recrystallized from methanol

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 27.5 g (0.1 mole) of N-(α,α-dimethylbenzyl) benzenesulfonamide was added to 5.8 g (0.12 mole) of 50% sodium hydride in 200 ml of dry N,N-dimethyl formamide. The mixture was stirred at room temperature for 30 minutes to react them. To the resulting sodium salt of N-(α,α-dimethylbenzyl)benzenesulfonamide was added 16.1 g (0.17 mole) of methyl bromide. The mixture was heated to 60° C. and stirred for 1 hour. The N,N-dimethyl formamide was distilled off under reduced pressure, and cold water was added. The resulting white solid was recrystallized from methanol to afford N-methyl-N-(α,α-dimethylbenzyl)benzenesulfonamide in a yield of 87%. This compound is designated as compound No. 64 in Table 2 below, and its melting point and elemental analysis values are shown in Table 2. to react them The mixture was heated to 60° C. stirred for 1 hour The N,N-dimethyl formamide was distilled off under reduced pressure, and cold water was added The resulting white solid was recrystallized from methanol
