Reaction Steps

A solution of ethyl-2-(3-phenylpropyl)-5-phenyl-2-pentenoate in methanol (10 mL) was added to a suspension of 10% palladium on carbon (0.112 g) in methylene chloride (10 mL) and the mixture was hydrogenated under 60 psi of hydrogen for 6 h. The catalyst was removed by filtration through a pad of celite and the solvent was removed under reduced pressure to give ethyl-2-(3-phenylpropyl)-5-phenyl-pentanoate (0.787 g, 98%). The crude product was not purified further but used directly in the next step. 1H NMR (300 MHz, CDCl3): δ 1.25 (t, 3 H, J=7.1), 1.60 (m, 8 H), 2.39 (m, 1 H), 2.61 (t, 4 H, J=7.3), 4.14 (q, 2 H, J=7.1), 7.24 (m, 10 H).
