چکیده
In the title compound, C17H17N5, the dihedral angle between the 1H-pyrazolo-[3,4-b]pyridine ring system (r.m.s. deviation = 0.001 Å) and the attached phenyl group is 2.56 (6)°. The propyl-amino side chain has a contorted conformation [Car-N-C-C = -77.97 (16)° and N-C-C-C = -57.37 (17)°]. An intra-molecular C-H⋯N inter-action closes an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds generate R 2 (2)(12) loops. Aromatic π-π stacking inter-actions [centroid-centroid distance = 3.5726 (8) Å] are also observed.
