Procedure

A mixture of 3-azidomethyl-4,4-difluoro-piperidine-1-carboxylic acid tert-butyl ester (1.1 mmol, 300 mg) and 10% palladium on carbon (60 mg) in EtOAc (8 mL) was stirred under an atmosphere of H2 for 2 hrs, filtered through celite, and concentrated to provide 3-aminomethyl-4,4-difluoro-piperidine-1-carboxylic acid tert-butyl ester.

Workup

  1. filtrationfiltered through celite
