Versuchsvorschrift
2-(Ethylthio)benzothiazole (1062 g, 0.056 mol) and ethyl p-toluensulfonate (11.15 g, 0.056 mol) were heated at 140°-167° C. for 2 hours. The mixture cooled and was dissolved in acetone. The acetone solution was poured into 400 ml anhydrous ether to yield 18.19 g (83%) of gummy solid.
