반응 단계
2-Methylbenzothiazole (300 pbw) and ethyl p-toluenesulfonate (440 pbw) 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 2000 pbw of acetone, and the product that precipitates is removed by filtration with suction, washed with acetone and dried over phosphorous pentoxide.
