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
摘要:
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)Å, V=2048.4(1)Å3, 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.
