Reaction Steps

Cysteamine hydrochloride (5.65 g; 50.0 mmoles) and 2-amino-4-chloromethylthiazole hydrochloride (9.25 g; 50.0 mmoles) were dissolved in 70 ml of concentrated hydrochloric acid and heated at an oil bath temperature of 105°. After 64 hours of heating the mixture was evaporated under reduced pressure and the residue triturated with acetone. The collected product was re-triturated with ethanol, filtered and dried to yield the title compound, mp 170°-200°.
