Abstract

In the title compound, C₂₄H₂₃N₃O₃S, the dihedral angle between the fused pyrazole and pyridine rings is 1.76 (7)°. The benzene and meth-oxy phenyl rings make dihedral angles of 44.8 (5) and 63.86 (5)°, respectively, with the pyrazolo-[3,4-b] pyridine moiety. An intra-molecular short S⋯O contact [3.215 (2) Å] is observed. The crystal packing features C-H⋯π inter-actions.

Keywords: C—H⋯π interactions; crystal structure; pyrazolo[3,4-b]pyridine; pyrazolopyridine.
