Synthesis and structure of ethyl 2-[(4-oxo-3-phenyl-3,4-di-hydro-quinazolin-2-yl)sulfan-yl]acetate.


ABSTRACT: The title compound, C18H16N2O3S, was synthesized by reaction of 2-mercapto-3-phenyl-quinazolin-4(3H)-one with ethyl chloro-acetate. The quinazoline ring forms a dihedral angle of 86.83?(5)° with the phenyl ring. The terminal methyl group is disordered by a rotation of about 60° in a 0.531?(13): 0.469?(13) ratio. In the crystal, C-H?O hydrogen-bonding inter-actions result in the formation of columns running in the [010] direction. Two parallel columns further inter-act by C-H?O hydrogen bonds. The most important contributions to the surface contacts are from H?H (48.4%), C?H/H?C (21.5%) and O?H/H?O (18.7%) inter-actions, as concluded from a Hirshfeld analysis.
