2-[2-(2-Anilino-4-oxo-3,4-dihydro-quinazolin-3-yl)phen-oxy]-3-phenyl-quinazolin-4(3H)-one methanol hemisolvate.


ABSTRACT: In the title compound, C(34)H(23)N(5)O(3)·0.5CH(3)OH, each pyrimid-in-one heterocycle and its adjacent benzene ring are almost coplanar, making dihedral angles of 0.69?(13) and 1.87?(13)°. The lower pyrimidinone ring makes a dihedral angle of 40.41?(15)° with the -NH- bonded phenyl ring. O-H?O hydrogen bonds and weak C-H?? inter-actions are observed in the crystal structure. The methanol solvent molecule is disordered over two positions of equal occupancy.
