Procedure

Hydrogenate 5-(1-azido-ethyl)-2-fluoro-pyridine (4.09 g, 24.59 mmol) under a 60 psi pressure in ethanol (200 mL) in presence of PtO2 (6% w/w). Filter the mixture after 4 hours, remove the solvent on a rotovap, and dry the resulting oil under vacuum to obtain the product (3.149 g). GCMS (EI) m/z 140 M+.

Workup
