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 inter­molecular inter­actions. The enaminone ring is disordered over two orientations with relative occupancies of 0.794 (4) and 0.206 (4).
