چکیده
In the title compound, C22H26N2O3, the piperidine ring exhibits a chair conformation. The phenyl rings attached to the piperidine at the 2- and 6-positions have axial orientations. These rings make a dihedral angle of 49.75 (11)°. The amino-oxy acetate group attached at the 4-position has an equatorial orientation. In the crystal, inversion dimers linked by pairs of C-H⋯π inter-actions occur.
