title: 6,7-Dihydro-4-(4-methoxy-phen-yl)-3-methyl-6-oxo-1-phenyl-1H-pyrazolo[3,4-b]pyridine-5-carbonitrile.
abstract: In the title compound, C(21)H(16)N(4)O(2), the dihedral angle between the meth-oxy-substituted benzene ring and the ring system formed by the pyridinone ring and the pyrazole ring is 57.4 (1)°, and that between the unsubstituted phenyl ring and the ring system is 135.6 (1)°. In the crystal structure, mol-ecules are linked together via inter-molecular N-H⋯O hydrogen bonds.
