Reaction Conditions

Reaction Steps

A mixture of 2.2 g of 1-[(tetrahydro-3-furanyl) methyl]-2-(nitroimino)hexahydropyrimidine, 0.58 g of sodium hydride (60%) and 100 ml of acetonitrile was stirred at 50° C. for 30 minutes. After this mixture was cooled on ice, 1.58 g of isobutanoyl chloride was added dropwise thereto over 30 minutes, and the mixture was then stirred at room temperature for 2 hours. After the completion of reaction, insolubles were removed by filtration, and concentration was then carried out under a reduced pressure. The resultant residue was purified by silica gel column chromatography (2:1 ethyl acetate/acetone) to obtain 1.30 g of 1-(isopropylcarbonyl)-2-(nitroimino)-3-[(tetrahydro-3-furanyl)methyl]hexahydropyrimidine
