3.65 g (23.5 moles) of cyanimino-dithiocarbonic acid dimethylester (purity: 94%) and 5.91 (30 moles) of N-(4-methoxybenzyl)-cysteamine are boiled in 30 ml of ethanol until the evolution of methyl mercaptan terminates. The reaction mixture is evaporated and the crystalline residue is recrystallized from 15 ml of isopropanol. 5.35 g (92%) of 2-cyanimino-3-(4-methoxybenzyl)-thiazolidine are obtained, melting at 99° to 102° C.
