Procedure

A solution of 2-guanidino-4-[4-(3-methylthioureido)butyl]thiazole in ethanol (15 ml.) is treated with the appropriate amount of maleic acid to give a solution containing 0.42 g. of the hydrogen maleate salt. This solution is treated with methyl iodide (0.17 g.) and the mixture heated under reflux for 1.5 hours. Concentration of the reaction mixture to 5 ml. and collection of the precipitated solid gives 2-guanidino-4-[2-(2,3-dimethylisothioureido)butyl]thiazole hydrogen maleate hydriodide.
