Ethyl 4-(3,4,6-trimethyl-1-phenyl-1H-pyrazolo[3,4-b]pyridin-5-yl)benzoate

Abstract

In the title compound, C24H23N3O2, the dihedral angles between the pyrazolopyridine ring system (r.m.s. deviation = 0.001 Å) and the N-bound and C-bound benzene rings are 15.95 (2) and 83.71 (4)°, respectively. The conformation of the former is influenced by an intramolecular C—H...N hydrogen bond, which generates an S(6) ring. In the crystal, stepped layers are generated by three sets of C—H...π interactions.
