Reaction Steps

[(3-tetrahydrofuryl)methyl]amine (38.0 g, 0.38 mole) and 56.99 g of water were mixed, and the resulting mixture was cooled to 5 degree centigrade. Furthermore, 3.05 g (0.07 mole) of 1N NaOH was added to the solution, and then N,O-dimethyl-N′-nitroisourea (49.2 g, 0.37 mole) was introduced to the solution. The suspension was stirred at 5 degree centigrade for 4 hours, and then heated to 10 degree centigrade, and further stirred for 10 hours. 35% hydrochloric acid (6.7 g, 0.07 mole) was added to the suspension so that the pH became not more than 4. Water and acetonitrile were added to the above suspension for complete dissolution. The resulting solution was analyzed by HPLC and as a result, the reaction yield of the titled compound was 86%.
