Methyl (3S,10b'S)-5-chloro-9′-fluoro-1-methyl-2-oxo-5′-phenyl-10b'H-spiro­[indoline-3,1′-pyrazolo­[3,2-a]iso­quinoline]-2′-carboxyl­ate

In the title compound, C₂₇H₁₉ClFN₃O₃, the pyrazole ring has a twist conformation and the six-membered ring to which it is fused has a screw-boat conformation. The mean plane of the pyrazole ring is inclined to the 2-methyl­indoline ring by 85.03 (9) and by 28.17 (8)° to the mean plane of the iso­quinoline ring system. In the crystal, mol­ecules are linked by pairs of C—H...F hydrogen bonds, forming inversion dimers. These dimers are linked via C—H...O hydrogen bonds, forming a two-dimensional network lying parallel to (10-1).
