The synthesis of the novel amino acid6-(hydroxymethyl)-2-piperidinecarboxylic acid (1a) and its ethyl ester 1b is reported. In the hydrogenation of 6-(hydroxymethyl)pyridine-2-carboxylates, hydrogenolysis of the alcohol group appeared as an unusual side reaction. Optimization of the reaction conditions allowed us to minimize hydrogenolysis and afforded pure 1.
