HCID 867386112-Ethylmercapto-3-ethylbenzoxazolium p-toluenesulfonate

Conditions

Temperature
150 °C

Procedure

A mixture of 3.0 g of 2-mercaptobenzoxazole and 12.0 g of ethyl p-toluenesulfonate was heated to 150° C. to react them for 6 hours. The reaction product was cooled to 80° C., and 25 ml of ethanol was added to it, thereby producing an ethanol solution of 2-ethylmercapto-3-ethylbenzoxazolium-p-toluenesulfonate.
