실험 절차

To 40 parts of tetrahydrofuran are added 1.5 parts of ethanolamine and 2.5 parts of triethylamine. Into this solution, 10 parts of tetrahydrofuran containing 5 parts of 2,4-dimethylbenzenesulfonyl chloride is dropped with stirring. After the dropping, the resultant mixture is stirred as it is for 30 minutes. Subsequently, the salt is removed by filtration, and the filtrate is freed from the solvent to form a solid. This solid is recrystallized from isopropyl ether to obtain 3.6 parts of N-2-hydroxyethyl-2,4-dimethylbenzenesulfonamide, m.p. 70°-72° C.
