In the molecule of the title compound, C18H16F2N4O2, the 1,2,4-triazole ring forms dihedral angles of 3.6 (2) and 14.9 (6)° with the 4-difluoromethoxy-substituted benzene ring and the 2,3-dimethyl-substituted benzene ring, respectively. The OCHF2 group is twisted away from the plane of the benzene ring, as shown by the C—O—C—C torsion angle of 145.8 (2)°. The conformation is stabilized by an intermolecular N—H⋯N hydrogen bond. In the crystal, short C—H⋯O interactions lead to chains of molecules.
