چکیده
The title compound, C(19)H(13)ClF(2)N(2)O(3), was prepared by the reaction of (Z)-ethyl 3-amino-3-(4-chloro-phen-yl)-2-cyano-acrylate and 2,6-difluoro-benzoyl chloride. The dihedral angle between the chloro-benzene and fluoro-benzene rings is 37.0 (1)°. The ethyl group is disordered over two positions [occupancies = 0.52 (2):0.48 (2)]. In addition to intra-molecular N-H⋯O and N-H⋯F hydrogen bonds, the crystal packing shows the mol-ecules to be connected by inter-molecular C-H⋯O and C-H⋯N hydrogen bonds.
