Reaction Conditions

Reaction Steps

To 20 parts of tetrahydrofuran is added 3.9 parts of N-methyl-ethanolamine. To this solution, 10 parts of tetrahydrofuran containing 5 parts of p-chlorobenzenesulfonyl chloride is added with stirring. After completion of the addition, the resultant mixture is stirred as it is for a while, and then heated for about 1 hour on a water bath at 50° C. to terminate the reaction. Then, the salt is removed by filtration, and the filtrate is freed from the solvent, whereby an oily substance is obtained. This oily substance is subjected to distillation under reduced pressure to obtain 4.2 parts of a distillate, b.p. 180° C./0.5 mmHg.
