The piperidine and cyclohexane rings in the title compound, C16H22N2O,
adopt a chair-chair conformation. The methyl group at N1 and the phen
yl ring at C2 are oriented equatorially while the rest of the molecule
is planar. The molecules are well stacked and the packing in the unit
cell is stabilized by O-H ... N hydrogen-bonded chains and weaker C-H
... O and C-H ... N bonds.
