Synthesis and Crystal Structure of 3-(4-Methoxyphenyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one
Synthesis of the title compound from 4-methoxyaniline was accomplished in three steps. The structure was supported by spectroscopic data and unambiguously confirmed by single crystal X-ray diffraction data. It crystallizes in the monoclinic space group P21 with unit cell dimensions a = 9.9349(8), b = 6.3377(5), c = 10.5783(10) Å, β = 97.752(3)°, V = 659.97(10) Å, Z = 2.

In the structure of title compound, C(22)H(20)O(2)N(2), the 11-membered benzodiazepine ring system adopts a distorted boat conformation. The benzene ring of this system forms dihedral angles of 89.69 (12) and 48.82 (12)° with those of the phenol and methoxy-phenyl substituents, respectively. The dihedral angle between the benzene rings is 49.61 (11)°. An intra-molecular O-H⋯N hydrogen bond gene...
