Several drops of formic acid and catalytic amount 5% Pd/C was added to a 25 mL flask charged with 10 mL methanol and 1.34 g (5 mmol) of 2. The reaction vessel was flushed with H2, 3 times, and then mounted with a H2 balloon. After two days of hydrogenolysis, the solute was filtered through a pad of silica, and concentrated to provide a yellow oil. 1.32 g (98%) product was collected. 1H NMR (CDCl3) δ 7.18 (s, 4H, ArH), 3.38 (m, 1H, ArCHCC), 2.60 (t, 2H, CCCH2CH2), 2.45-1.91 (m, 6H, cyclo-pentyl), 1.64-1.15 (m, 12H, CH2), 0.90 (t, 3H, CH3); 13C NMR (CDCl3) δ 220, 142, 140, 129, 127, 46, 42, 39, 36, 32, 32, 32, 30, 30, 29, 23, 14.
