Participants

Reaction Steps

To a solution of 3-(3′,6′-Dihydro-2′-H-[2,4′]bipyridinyl-1′-yl)-propylamine (3.48 g crude, 15.9 mmol) in MeOH (40 mL), was added 1.0 g of Pearlman's catalyst. The suspension was hydrogenated under 120 psi for 10 h after which the reaction mixture was filtered through a pad of celite and the solvent was removed. The residue was purified by column chromatography over silica gel using CH2Cl2/methanol/2M NH3 in MeOH (90:8:4 to 90:40:40) as the eluting system. The product was obtained as a pale yellow oil (3.21 g, 91%).
