Synthesis and Crystal Structure of Ethyl 4-(3,4-Methylenedioxylphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyridine-5-carboxylate under Microwave Irradiation

The crystal structure of the title compound (C16H17NO5) has been determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group C2/c with a = 18.520(2), b = 7.8910(1), c = 21.728(3) A, β = 104.77(1)°, V= 3070.4(7) A3, Mr= 303.31, Z = 8, Dc= 1.312 g/cm3, λ = 0.71073 A,μ(MoKα) = 0.098 mm-1 and F(000) = 1280. The structure was refined to R = 0.0486 and wR = 0.1287. There exist intermolecular hydrogen bonds in the crystal.
