Procedure

To a suspension of 5% Pd/C in EtOAc was added a solution of 5-(1-azido-2-ethylbutyl)-1-(4-fluorobenzyl)-1H-1,2,4-triazole in EtOAc and the mixture was shaken on a Parr apparatus for 2 h under 3 atm of H2. The mixture was filtered through Celite, washed several times with EtOAc, concentrated in vacuo, and purified by column chromatography (SiO2, EtOAc, then, MeOH/EtOAc, 1:9, then 1:4) to yield 68% of the amine.
