Abstract

In the title compound, C17H17N5, the dihedral angle between the 1H-pyrazolo[3,4-b]pyridine ring system (r.m.s. deviation = 0.001 angstrom) and the attached phenyl group is 2.56 (6)degrees. The propylamino side chain has a contorted conformation [C-ar-N-C-C = -77.97 (16)degrees and N-C-C-C = -57.37 (17)degrees]. An intramolecular C-H center dot center dot center dot N interaction closes an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H center dot center dot center dot N hydrogen bonds generate R-2(2) loops. Aromatic pi-pi stacking interactions [centroid-centroid distance = 3.5726 (8) angstrom] are also observed.
