実験手順
5-Chloro-2-mercaptobenzothiazole (20.17 g, 0.1 mol) in 55 ml 95% ethanol was treated with 10.1 g (0.1 mol) triethylamine to give a brown solution. Iodoethane (15.6 g, 0.1 mol) was added and the mixture refluxed 67 minutes. The mixture was cooled and poured into 300 ml water to precipitate a solid. The aqueous phase was extracted 3×50 ml methylene chloride. The organic extracts were combined with solid precipitate, washed with water, dried over Na2SO4, filtered, and rotary evaporated to give brown solid. Recrystallization from isopropanol yielded 12.26 g (53%) brown crystals, mp 49°-50° C.
