Intermediate 1-[2-Benzyl-4-(3-cyclopentyloxy-4-methoxy-phenyl)-piperazin-1-yl]-2-benzyloxy-ethanone (60 mg, 0.12 mmol) was dissolved in MeOH (20 mL), purged with a stream of nitrogen, treated with 20% Pd/C (140 mg, 50% water content) and hydrogenated under 40 psi pressure of hydrogen for 4 h. The crude reaction mixture was then purged with nitrogen, filtered, evaporated, and purified by silica gel flash chromatography with 40% then 75% EtOAc/hexane as eluant to afford the title compound as an oil (9 mg, 18%). LC/MS (Method A) 6.55 min, [M+1]+ 425.
