10 ml of ethyl acetate was added to a mixture of 180 mg (0.330 mmol) of 6-(2-azidoethoxymethyl)-4-(3-chlorophenyl)-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid (3,3-diphenylpropyl)amide and a catalytic amount of 10% palladium/carbon, and they were stirred at room temperature in hydrogen atmosphere under normal pressure overnight. The catalyst was filtered out, and the filtrate was concentrated under reduced pressure. The residue was purified by the basic silica gel chromatography (dichloromethane/methanol=100/1 to 20/1) to obtain the title compound.
