Four 6-substituted 2-methyl-3-ethoxycarbonyl-4-quinolinones were synthesized by using microwave technique under solvent-free conditions. Their structures were characterized by FTIR and elemental analysis and characterized by X-ray The crystal structure of the title compound with the methoxy group as the substituent is determined by the diffraction method. The crystal belongs to monoclinic space group P21 / n, a = 0.67780 (14) nm, b = 0.68990 (6) nm β = 92.34 (3) ° V = 1.2769 (5) nm3 Z = 4 Mr = 261.27 Dc = 1.359g / cm3 μ = 0.100mm-1 S = 1.097 F ) = 552, the final deviation factor is R1 = 0.087, wR2 = 0.200.
