The title compound, C23H24FN3O, crystallizes with two independent molecules (I and II) in the asymmetric unit. These pairs of molecules are linked to each other as N-H center dot center dot center dot O dimers with an R-2(2) (10) motif. Furthermore, the crystal structure also exhibits C-H center dot center dot center dot pi interactions. The atoms of the ethyl group in molecule I are disordered over two sites with an occupancy ratio of 0.817 (6):0.183 (6).
