摘　　要：The title compound 4-(3,4-methylenedioxylphenyl)-6-methyl-5-ethoxycaronyl-3,4- dihydropyrimidin-2(H)-one (C15H16N2O5) has been synthesized and determined by single-crystal X-ray diffraction. The crystal is of triclinic, space group P with a = 7.580(1), b = 7.920(2), c = 13.168(4) ? a = 96.44(2), b = 96.71(2), g = 109.81(2), V = 728.8(3) 3, Z = 2, Mr = 304.30, Dc = 1.387 g/cm3, F(000) = 320, m(MoKa) = 0.105 mm-1 (l = 0.71073 ?, R = 0.0446 and wR = 0.1205. In the molecule the pyrimidine ring adopts a boat conformation.The title compound 4-(3,4-methylenedioxylphenyl)-6-methyl-5-ethoxycaronyl-3,4- dihydropyrimidin-2(H)-one (C15H16N2O5) has been synthesized and determined by single-crystal X-ray diffraction.
