2-Methyl-3-(2-methyl­phen­yl)-4-oxo-3,4-dihydro­quinazolin-8-yl thio­phene-2-carboxyl­ate

In the title compound, C(21)H(16)N(2)O(3)S, the central quinazolin-4-one ring is planar (r.m.s. deviation = 0.037 Å). The N-bound benzene and thio­phenyl rings are almost perpendicular to the central plane [dihedral angles = 82.22 (5) and 77.05 (13)°, respectively]. Mol­ecules are connected into a t...

description In the title compound, C(21)H(16)N(2)O(3)S, the central quinazolin-4-one ring is planar (r.m.s. deviation = 0.037 Å). The N-bound benzene and thio­phenyl rings are almost perpendicular to the central plane [dihedral angles = 82.22 (5) and 77.05 (13)°, respectively]. Mol­ecules are connected into a three-dimensional array by C—H⋯O inter­actions involving both carbonyl O atoms. The thio­phene ring is disordered over two positions, which are approximately parallel and oppositely orientated. The major component refined to a site-occupancy factor of 0.6555 (17).
