A solution of 5-fluoro-3-(2-pyridin-3-yl-vinyl)-1H-indole (3 mmol) in MeOH (10 mL) is treated with Pd/C (200 mg) and shaken in a Parr apparatus under 40 atm of H2 for 18 h. The mixture is filtered through Celite and the filtrate is concentrated in vacuo. The residue is purified by silica gel chromatography eluting with 0%-10% MeOH in DCM to afford 5-fluoro-3-(2-pyridin-3-yl-ethyl)-1H-indole (360 mg, 50%, 2 steps).
