The title compound, C(10)H(19)NO(3), is a disubstituted piperidine bearing substituents in two equatorial positions. One of the substituents is a hy-droxy group bound to nitro-gen and the second a tert-butyl ester group bound to the carbon next to the endocyclic nitro-gen. Enanti-omers of the title compound form hydrogen-bridged dimers across a center of inversion.
