Ethyl 2-anilino-4-methyl-5-[5-methyl-1-(4-methylphenyl)-1H-1,2,3-triazole-4-carbonyl]thiophene-3-carboxylate

Abstract

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].
