실험 절차
5-Methoxy-2-(methylthio)benzothiazole (7 g, 0.033 mol) and methyl p-toluenesulfonate (6.77 g, 0.036 mol) were heated to 128°-163° C. for 22 minutes. The resulting solid, after cooling, was triturated with acetone, filtered, and acetone washed until washings were colorless, yielding 12.13 g (96%).
