In the title compound, C22H18N2O, the phenyl and tolyl rings make dihedral angles of 84.71 (7) and 65.11 (6)°, respectively, with the isatin group. The aromatic rings make a dihedral angle of 60.90 (8)°. The imino C=N double bond, exists in an E conformation. In the crystal, mol­ecules are linked by weak π–π stacking inter­actions [centroid–centroid distance = 3.6598 (13) Å].
