2,4-Bis(2-bromophenyl)-7-tert-pentyl-3-azabicyclo[3.3.1]nonan-9-one

The title compound, C25H29Br2NO, is a tert-pentyl analog of 2,4-bis(2-bromophenyl)-3-azabicyclo[3.3.1]nonan-9-one [Parthiban et al. (2008). Acta Cryst. E64, o2385]. Similar to its analog, the title compound exists in a twin-chair conformation with an equatorial orientation of the 2-bromophenyl groups. The benzene rings are inclined to each other at a dihedral angle of 29.6 (3)°. The tert-pentyl group on the cyclohexanone ring also adopts an exocyclic equatorial disposition.
