実験手順
A mixture of 2-guanidino-4-[2-(3-cyano-2-methylisothioureido)ethylthiomethyl]thiazole (1.1 g.) in ethanol (25 ml.) was treated with 70% w/v aqueous ethylamine (5 ml.) at room temperature. The mixture was stirred overnight at room temperature and the solution evaporated to dryness. The residue was crystallized from methanol to give 2-guanidino-4-[2-(2-cyano-3-ethylguanidino)ethylthiomethyl]thiazole (0.53 g.), m.p. 181°-182° C.
