Procedure

11.6 g (0.1 mol) of pseudothiohydantoin was suspended in 150 ml of dimethylformamide, and 17 g (0.12 mol) of methyl iodide was added thereto. Then, the mixture was stirred at 60° C. for one hour. After being left to cool, the reaction mixture was poured into 1000 ml of ethyl acetate, and precipitated crystals were collected by filtration to obtain 15 g of 3-methyl-2-iminothiazolidin-4-one hydroiodide as pale yellow crystals.
