Reaktionsschritte

102 mg (0.329 mmol) of 3-carbamoyl-4-(3-chlorophenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid and 83.5 mg (0.395 mmol) of (3,3-diphenylpropyl)amine were dissolved in 10 ml of DMF. 94.6 mg (0.494 mmol) of WSC hydrochloride was added to the obtained solution under cooling with ice, and they were stirred at room temperature overnight. After the concentration under reduced pressure, the reaction mixture was diluted with ethyl acetate and then washed with 1 N hydrochloric acid, saturated aqueous sodium hydrogencarbonate solution and saturated aqueous sodium chloride solution. The organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by the basic silica gel chromatography (dichloromethane/methanol=100/1 to 10/1) to obtain the crude title compound.
