Reaction Steps

An intimate mixture of 2-(2-aminoethyl)thiazole (4.5 g) and S-methylthiouronium sulphate (9.8 g) is heated at 140°-150° C for one hour. Extraction with ethanol and cooling affords the crude product, m.p. 130°-135° C. Recrystallization from ethanol gives 2-(2-thiazolyl)ethylguanidine hemisulphate, m.p. 143°-145° C.
