Abstract
In the title compound, C26H21N3O, the phenyl ring of the 4-aminoantipyrine group and the heterocyclic five-membered ring along with its substituents, except for the N-bound methyl group (r.m.s. deviation = 0.0027 angstrom), form a dihedral angle of 54.20 (5)degrees. Two S(6) ring motifs are formed due to intramolecular C-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds. In the crystal, molecules are linked into supramolecular chains along the a-axis direction via C-H center dot center dot center dot O contacts.
