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

Abstract: 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).
