Procedure

A mixture of the cyanoester from step 3 (2.89 g, 8 mmol) and 10%, Pd--C (0.6 g, DeGussa, H2O content 50%) in anhyd MeOH (35 mL) was hydrogenated for 2 h (42-26 psi). The reaction mixture was filtered through a Celite® pad and concentrated to a colorless oil (2.02 g). 1H NMR (300 MHz, CDCl3) δ 2.35(t, 8 Hz, 2H), 2.20 (m, 1H), 2.00 (m, 1H), 1.3-1.9(m, 22H).
