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).
在标题化合物C(19)H(22)F(3)NO(4)中,苯环与烯胺酮环共轭部分之间的二面角为42.5 (1)°。酯取代基与后一个部分的二面角为81.3 (2)°。晶体结构通过强N-H⋯O和弱C-H⋯O分子间相互作用维系在一起。烯胺酮环在两个取向间无序分布,相对占有率分别为0.794 (4)和0.206 (4)。
