Sulfuric Acid → 2-(2-Benzothiazolylthio)propanamide

Participants

Reaction Steps

A finely powdered mixture of 16.8 g of 2-mercaptobenzothiazole and 7.5 g of acrylic amide is added at 45°-50° in the course of 1 hour to 100 ml 70% sulfuric acid, with stirring. After a further hour at 45°-50°, the rection mixture is poured into ice water. The precipitate is filtered off, washed with water and dried. The obtained 2-(benzthiazol-2-ylthio)-propionic acid amide is recrystallized from ethylacetate and melts at 144°-145°.
