Reaction Steps

[(3-tetrahydrofuryl)methyl]amine (38.0 g, 0.38 mole), 31.3 g of sodium chloride and 125.0 g of water were mixed, and the resulting mixture was cooled to −10 degree centigrade. N,O-dimethyl-N′-nitroisourea (49.2 g, 0.37 mole) was introduced into the above solution. Sodium chloride was dissolved in water with 76% of the saturated solubility at a water temperature of −10 degree centigrade. The suspension was stirred at −10 degree centigrade for 4 hours and then heated to 10 degree centigrade, and further stirred for 19 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 88%.
