Abstract

An economically benign solvent-free approach to synthesise 2,3-dimethylbenzoxazolium methosulfate is reported in the present work. The title compound is derived from 2-methylbenzoxazole reacting with a slight excess of dimethylsulfate, at room temperature. The reaction proceeds via an intrinsic exothermic reaction, and the benzoxazolium salt crystallized after a short time into a white crystalline form. The product was filtered off and washed with acetone and diethyl ether to provide the desired product in 89% yield. The target compound was evaluated by ESI/MS analysis. View Full-Text
