The conformation of the title compound, C25H24N4O3S, is influenced by an intramolecular N—H⋯O hydrogen bond, which generates an S(6) ring. The twist angles between the planes through the toluyl, methyltriazole, thiophene and phenyl rings are 60.1 (1), 33.5 (1) and 39.9 (1)°, respectively. In the crystal, molecules are stacked along the a-axis direction with weak aromatic π–π stacking interactions occurring between the thiophene rings [centroid-to-centroid distance = 3.7285 (15) Å].

Structure description
Substituted 2-aminothiophenes are found in numerous biologically active compounds including olanzapine as an antipsychotic drug and tinoridine as a potent nonsteroidal anti-inflammatory drug (Al-Taisan et al., 2010; Huang & Dömling, 2011; Wardakhan et al., 2016). As part of our studies of similar systems, we now describe the structure of the title compound.
The 25H24N4O3S (Fig. 1). An intramolecular N—H⋯O hydrogen bond occurs in the molecule (Table 1) and the twist angles between the planes through the toluyl, methyltriazole, thiophene and phenyl rings are 60.1 (1)°, 33.5 (1)° and 39.9 (1)° respectively. In the crystal, molecules are stacked along the a-axis and π–π type interactions involving thiophene groups of neighbouring molecules with centroid-to-centroid distances of 3.7285 (15) Å are observed (Fig. 2); the pairs are related by a twofold rotation axis.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Non-hydrogen atoms were refined with anisotropic displacement parameters. All hydrogen atoms were placed in calculated positions and refined using a riding model. Methyl C—H bonds were fixed at 0.96 Å, with displacement parameters 1.5 times Ueq(C), and were allowed to spin about the C—C bond. Methylene C—H bonds were fixed at 0.97 Å with displacement parameters 1.2 times Ueq(C). The N—H bond was fixed at 0.86 Å and aromatic C—H distances were set to 0.93 Å and their U(iso) set to 1.2 times the Ueq for the atoms to which they are bonded. |
