Crystal structure of 3-{5-[3-(4-fluoro­phen­yl)-1-isopropyl-1H-indol-2-yl]-1H-pyrazol-1-yl}indolin-2-one ethanol monosolvate

The title indolin-2-one compound, C(28)H(23)FN(4)O·C(2)H(6)O, crystallizes as a 1:1 ethanol solvate. The ethanol mol­ecule is disordered over two positions with refined site occupancies of 0.560 (14) and 0.440 (14). The pyrazole ring makes dihedral angles of 84.16 (10) and 85.33 (9)° with the indolin-2-one and indole rings, respectively, whereas the dihedral angle between indolin-2-one and indole rings is 57.30 (7)°. In the crystal, the components are linked by N—H⋯O and O—H⋯O hydrogen bonds, forming an inversion mol­ecule–solvate 2:2 dimer with R (4) (4)(12) ring motifs. The crystal structure is consolidated by π–π inter­action between pairs of inversion-related indolin-2-one rings [inter­planar spacing = 3.599 (2) Å].
