2,4-Bis(2-methoxy-phenyl)-3-aza-bicyclo-[3.3.1]nonan-9-one.

In the title compound, C(22)H(25)NO(3), the mol-ecule has a pseudo-mirror plane. The structure is a positional isomer of 2,4-bis(4-methoxy-phenyl)-3-aza-bicyclo-[3.3.1]nonan-9-one [Cox, McCabe, Milne & Sim (1985 ▶). J. Chem. Soc. Chem. Commun. pp. 626-628]. The 3-aza-bicyclo-[3.3.1]nonan-9-one moiety adopts a double chair conformation with equatorial orientations of both 2-methoxy-phenyl substituents on either side of the secondary amino group. The benzene rings are oriented at an angle of 33.86†(4)° with respect to each other and the meth-oxy groups point towards the carbonyl group. The crystal structure is stabilized by intermolecular N-H⋯π inter-actions.
