9.04 g (80 mmol) of creatinine was suspended in 50 ml of dimethylformamide, and 17.0 g (100 mmol) of n-propyl iodide was added thereto. Then, the mixture was heated and stirred within a range of from 70° C. to 80° C. until creatinine was completely dissolved. The mixture was left to cool, and 500 ml of ethyl acetate was added thereto. Precipitated crystals were collected by filtration to obtain 10.6 g of 1-methyl-3-n-propyl-2-iminoimidazolidin-4-one hydroiodide.
