반응 단계
300 g (2 mol) of 2-methylbenzothiazole and 440 g (2.2 mol) of ethyl p-toluenesulfonate (or a mixture of ethyl o- and p-toluenesulfonate) are heated with stirring to 150° C., the temperature rising to about 200° C. due to the exothermic reaction. After 10 minutes, the mixture is poured into two liters of acetone, and the product which has precipitated is filtered off with suction, washed with acetone and dried in vacuo. Yield 730 g (98%).
