5,6-Dimethyl-4-(thio­phen-2-yl)-1H-pyrazolo­[3,4-b]pyridin-3-amine

In the title mol­ecule, C(12)H(12)N(4)S, the thio­phene ring is disordered over two orientations with a refined site-occupancy ratio of 0.777 (4):0.223 (4). The pyrazolo­pyridine ring system is essentially planar with an r.m.s. deviation of 0.0069 (3) Å and makes dihedral angles of 82.8 (2) and 72.6 (5)°, respectively, with the major and minor components of the thio­phene ring. In the crystal, mol­ecules are linked into a chain along the a axis by a pair of N—H⋯N(pyrazole) hydrogen bonds and a pair of N—H⋯N(pyridine) hydrogen bonds, both having a centrosymmetric R (2) (2)(8) graph-set motif. A C—H⋯π inter­action is also present.
