Reaction Conditions

Reaction Steps

111 mg (0.234 mmol) of 4-(3-chlorophenyl)-2-methoxyl-6-methyl-1,4-dihydropyrimidine-5-carboxylic acid (3,3-diphenylpropyl)amide was dissolved in 5 ml of ethanol. 67.4 mg (0.702 mmol) of ammonium carbonate and 11.8 mg (0.187 mmol) of ammonium acetate were added to the obtained solution, and they were stirred at 80° C. for 2 days. The reaction mixture was diluted with ethyl acetate. An insoluble matter thus formed was filtered out, and the filtrate was concentrated under reduced pressure. The residue was purified by the basic silica gel chromatography (100% dichloromethane) to obtain the title compound.
