1,4-Dimethyl-2-phenyl-6,7-dihydro-1H-pyrazolo[4,3-b]pyridine-3,5(2H,4H)-dione
Abstract
The mean plane of the pyrazolone ring [maximum deviation = 0.054 (1) Å] of the title compound, C14H15N3O2, is oriented at a dihedral angle of 36.05 (7)° with respect to the phenyl ring. The methyl group is slightly disposed [distance = 0.864 (2) Å] out of the mean plane of the pyrazolone ring to which it is attached.
