3-Hy-droxy-1-methyl-2-[4-(piperidin-1-yl)phen-yl]quinolin-4(1H)-one.

ABSTRACT: There are two structurally similar but crystallographically independent mol-ecules (A and B) in the asymmetric unit of the title compound, C(21)H(22)N(2)O(2), which are linked via two O-H⋯O hydrogen bonds. An intramolecular O-H⋯O hydrogen bond also occurs in each molecule. In the crystal, the A and B mol-ecules are further linked through C-H⋯O inter-actions. The benzene ring is twisted at an angle of 69.9 (1) and 83.4 (1)° relative to the 1,4-dihydro-quinoline skeleton in mol-ecules A and B, respectively. Adjacent 1,4-dihydro-quinoline units of mol-ecules A are parallel, while mol-ecules A and B are oriented at an angle of 32.8 (1)°.
