2-Bromo-5,7-dimeth-oxy-4-phenyl-quinoline.

ABSTRACT: The title compound, C(17)H(14)BrNO(2), was synthesized by the treatment of 5,7-dimeth-oxy-4-phenyl-quinolin-2-one with phosphoryl bromide in a Vilsmeier-type reaction. There are two independent mol-ecules (A and B) in the asymmetric unit which differ by 11.2° in the orientation of the 4-phenyl ring with respect to the planar quinoline ring system [dihedral angles = 55.15?(8) and 66.34?(8)° in mol-ecules A and B, respectively]. In the crystal structure, the independent mol-ecules are linked via C-H?N and C-H?O hydrogen bonds, forming centrosymmetric tetra-meric units which are cross-linked through C-H?? and C-Br?? inter-actions with Br?centroid distances of 3.4289?(8) and 3.5967?(8)?Å.
