RESUMEN
The title compound, C(17)H(23)NO(2), contains two chiral centres and was synthesized from 2-(3-acetyl-2,2-dimethyl-cyclo-butyl)acetic acid and m-toluidine. The cyclobutane ring is not flat but flexed as though folded from the dimethyl-substituted C atom to the unsubstituted C atom, with a dihedral angle of 25.9°. The crystal structure is stabilized by N-Hâ¯O and C-Hâ¯O hydrogen-bonding inter-actions.
