title: tert-Butyl 3-carbamoyl-4-methoxy-imino-3-methyl-piperidine-1-carboxyl-ate.
abstract: In the title compound, C(13)H(23)N(3)O(4), the piperidine ring adopts a chair conformation. An intra-molecular N-H⋯O hydrogen bond is observed between the carbamoyl and carboxyl-ate groups. In the crystal structure, mol-ecules form inversion dimers linked by pairs of N-H⋯O hydrogen bonds.
