tert-Butyl N-[(3R,4R)-1-(2-cyanoacetyl)-4-methylpiperidin-3-yl]-N-methylcarbamate

Abstract

The piperidine ring of the title compound, C15H25N3O3, adopts a slightly distorted chair conformation with the cis substituents displaying an N—C—C—C torsion angle of 43.0 (3)°. The cyano group (plane defined by C—C—C[triple-bond]N atoms) is bent slightly out of the plane of the amide group by 13.3 (2)°. The carbamate group is oriented at a dihedral angle of 60.3 (5)° relative to the amide group.
