Reaction Steps

A mixture of tert-butyl (3R)-3-{[3-chloro-5-(hydroxymethyl)-2-pyridinyl]amino}-1-piperidinecarboxylate (10.0 g) and MnO2 (25.4 g) in CHCl3 (200 ml) was stirred at 60° C. for 3.5 hours. After removal of the insoluble material, and the solvent was evaporated in vacuo to give tert-butyl (3R)-3-[(3-chloro-5-formyl-2-pyridinyl)amino]-1-piperidinecarboxylate (9.08 g).
