Procedure

A solution of 4-methyl-5-[(2-aminoethyl)thiomethyl]imidazole (1.71 g.) and thiazolidine-2-one-4-thione (1.33 g.) in methanol (30 ml.) was heated under reflux for one hour. Concentration, followed by successive recrystallisation of the residue from methanol, ethanol and aqueous ethanol afforded 4-[2-((4-methyl-5-imidazolyl)methylthio)ethylamino]thiazoline-2-one (1.0 g.) m.p. 195°-197°.
