摘要
The title compound （C19H15NO6） was synthesized via a three-component reaction and characterized by means of IR and 1H NMR. Its crystal and molecular structures were determined by X-ray diffractometry. It belongs to the monoclinic system, space group P21/c with a = 11.670（3）, b = 12.076（3）, c = 11.613（3）, β = 99.490（4）°, V = 1614.2（7）3, Mr = 353.32, Z = 4, Dc = 1.454 g/cm3, λ = 0.71073, μ = 0.110 mm-1, F（000） = 736, the final R = 0.0503 and wR = 0.1311. A total of 8454 reflections were collected, of which 3497 were independent （Rint = 0.0333） and 2102 were observed with I 2σ（I）.
