Crystal structure of 9-(4-bromobutyl)-9H-fluorene-9-carboxylic acid
The title compound, C18H17BrO2, is a key inter-mediate in the synthesis of lomitapide mesylate, a microsomal triglyceride transfer protein inhibitor. Its asymmetric unit contains two independent mol-ecules with slightly different conformations; the mean planes of the 4-bromo-butyl and carboxyl-ate groups in the two mol-ecules form dihedral angles of 24.54 (12) and 17.10 (18)°. In the crystal, c...

In the title compound, C(28)H(21)Cl, the dihedral angle between the two fluorene ring systems is 71.97 (4)°. There is an intra-molecular C-H⋯Cl hydrogen bond. In the crystal structure, the centroid-to-centroid distance between stacked fluorene ring systems is ca 4.22 Å, which indicates that there are no π-π stacking inter-actions between them.

In the title carbazole derivative, C32H32N2, the mol-ecule resides on a crystallographic twofold axis, which runs through the central C-C bond. The carbazole ring system is almost planar, with a maximum deviation of 0.041 (1) Å for one of the ring-junction C atoms. The crystal packing is stabilized by C-H⋯π inter-actions only, which form a C(7) chain-like arrangement along [110] in the unit cell.
