100 g of cyanomethylurea is combined with a mixture of 300 ml of methanol and 5 ml of 8N sodium hydroxide solution and stirred for 3 hours at 25°30° C. The mixture is allowed to cool to 20° C., the resultant product is removed by filtration, washed with a small amount of ice-cold methanol, and dried under vacuum, thus obtaining 92.6 g of (2-methoxy-2-iminoethyl)urea (=70% of theory).
