Synthesis and Crystal Structure of 1-Ethyl 3-Methyl 6-Benzyl-2-methyl-5-oxo-5,6-dihydropyrrolo[1,2-c]quinazoline-1,3-dicarboxylate

The crystal structure of the title compound(C24H22N2O5, Mr = 418.44) has been determined by single-crystal X-ray diffraction. The crystal is of orthorhombic, space group P21/c with a = 7.751(2), b = 12.392(4), c = 21.326(6), V = 2048.4(1)3, Z = 4, Dc = 1.357 g/cm3, F(000) = 880, μ(MoKα) = 0.096 mm-1, the final R = 0.0731 and wR = 0.1982 for 3335 observed reflections(I 2σ(I)). Intermolecular C(24)–H(24B)···O(1) hydrogen bond is observed in the structure.
