The title compound, C(19)H(17)ClF(3)NO, was synthesized from 3-[(E)-2-chloro-3,3,3-trifluoro-prop-1-en-yl]-2,2-dimethyl-cyclopropane-carboxylic acid and 2-aminona-phthalene. There are two molecules in the asymmetric unit. The dihedral angle between the naphthalene and cyclo-propane units is 111.6 (5)°. Molecules are connected into chains by intermol-ecular N-H⋯O hydrogen bonds. One of the Cl atoms is disordered over two positions with occupancies 0.653 (15) and 0.347 (15).
