6,7-Dihydro-4-(4-methoxyphenyl)-3-methyl-6-oxo-1-phenyl-1H-pyrazolo[3,4-b]pyridine-5-carbonitrile

Abstract

In the title compound, C21H16N4O2, the dihedral angle between the methoxy-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, molecules are linked together via intermolecular N—H...O hydrogen bonds.
