실험 절차
Cysteamine hydrochloride (5.24 g; 45.9 mmoles) and 2-dimethylamino-4-chloromethylthiazole hydrochloride (9.8 g; 45.9 mmoles) [prepared from N,N-dimethylthiourea and 1,3-dichloro-2-propanone] were dissolved in 45 ml of concentrated hydrochloric acid and heated at an oil bath temperature of 100° for 96 hours. The mixture was evaporated under reduced pressure and the residue made basic with 40% aqueous NaOH. The aqueous phase was extracted with methyl acetate, dried and evaporated to give the title compound as an oil which was used without further purification in Step B.
