5-(1-Phenyl-1,2,3,6-tetrahydropyridin-4-yl)indolin-2-one → 5-(1-Phenylpiperidin-4-yl)indolin-2-one

Participants

Reaction Steps

To a solution of 5-(1-phenyl-1,2,3,6-tetrahydropyridin-4-yl)indolin-2-one (75.8 mg, 0.261 mmol) in THF (3 ml) and MeOH (3 ml) was added 10% Pd/C (210 mg) and stirred at room temperature under H2 (1 atom) atmosphere for 2 h. The reaction mixture was filtered through a Celite pad and concentrated. The residue was purified by column chromatography (CHCl3/MeOH) to afford 5-(1-phenylpiperidin-4-yl)indolin-2-one (51.2 mg) as mixture of triphenylphosphine oxide.
