A solution of (2S)-2-((3R)-3-(4-(2-methoxyphenyl)piperidin-1-yl)-2-cyclopropylpyrrolidin-1-yl)-2-phenylethanol (preparation #26) (1.708 g, 4.06 mmol) in EtOH (25 mL) was hydrogenated under hydrogen at about 60 bar at about 60° C. in a H-cube™ apparatus using palladium hydroxide on carbon (20%) as a catalyst until all starting material was converted to product. The solvent was removed in vacuo to afford 1-((3R)-2-cyclopropylpyrrolidin-3-yl)-4-(2-methoxyphenyl)piperidine (1.23 g, 4.09 mmol) as an orange oil. RP-HPLC (Table 1, Method a) Rt 1.48 min; m/z: (M+H)+ 301.
