Participants

Reaction Steps

5-Chloro-2-(ethylthio)benzothiazole (11.5 g, 0.05 mol) and 10.55 g ethyl p-toluenesulfonate were heated at 150°-160° C. for 2 hours. After cooling, the product was dissolved in acetone and poured into 400 ml stirred anhydrous ether. The resulting precipitated oil crystallized upon scraping with a spatula. The ether was decanted, the solid triturated with ether, and the ether again decanted to yield 11.04 g (51%) after air drying.
