In the title compound, C(19)H(22)F(3)NO(4), the dihedral angle between the benzene ring and the conjugated part of the enaminone ring is 42.5 (1)°. The ester substituent makes a dihedral angle of 81.3 (2)° with this latter moiety. The crystal structure is held together by strong N-H⋯O and weak C-H⋯O inter-molecular inter-actions. The enaminone ring is disordered over two orientations with relative occupancies of 0.794 (4) and 0.206 (4).
