Participants

Reaction Steps

A saturated solution of phosgene in ethyl acetate (1200 ml) is charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. 2-Aminobenzothiazole (100.0 grams; 0.67 mole) is then added with stirring. After the addition is completed, the reaction mixture is heated at reflux for a period of about one hour. After this time the reaction mixture is evaporated to dryness to yield the desired product benzothiazol-2-yl isocyanate dimer as a yellow solid having a melting point of 250° to 252° C.
