Abstract
The title compound, C19H13ClF2N2O3, was prepared by the reaction of (Z)-ethyl 3-amino-3-(4-chlorophenyl)-2-cyanoacrylate and 2,6-difluorobenzoyl chloride. The dihedral angle between the chlorobenzene and fluorobenzene rings is 37.0 (1)°. The ethyl group is disordered over two positions [occupancies = 0.52 (2):0.48 (2)]. In addition to intramolecular N—H⋯O and N—H⋯F hydrogen bonds, the crystal packing shows the molecules to be connected by intermolecular C—H⋯O and C—H⋯N hydrogen bonds.
