    microwave irradiation,3,4-dihydropyrimidinone,H3BO3,crystal structure


    The title compound 4-(4-chlorophenyl)-6-methyl-5-methoxy-caronyl-3,4-dihydro- pyrimidin-2(H)-one has been synthesized by the reaction of 4-chlorobenzaldehyde, methyl acetoa- cetate and urea using H3BO3 as a catalyst under microwave irradiation. Its structure was charac- terized by X-ray single-crystal diffraction techniques with the following data: triclinic, space group P, a = 5.4513(4), b = 7.619(1), c = 16.118(4) A, α= 80.42(1),β= 83.43(1),γ= 79.29(1)0, V = 646.1919 A3, Mr = 280.70, μ(MoKα) = 0.301 mm-1, Z = 2 and Dc = 1.443 g/cm3. In the molecule the pyrimidine ring is of boat conformation.
