Combine 1-(3,4,5-trimethoxy-benzoyl)-3-[2-[4-[1H-benzoimidazole-2-carbonyl]-piperidin-1-yl]-ethyl]-3-phenyl-pyrrolidine (0.62 g, 1.0 mmol), and 2-(3,3-dimethylallyloxy)-ethanol (0.14 g, 1.0 mmol), triphenylphosphine (0.33 g, 1.27 mmol) in tetrahydrofuran (2 mL). Add dropwise diethyl azodicarboxylate ((0.2 mL, 1.27.mmol). After 18 hours, evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with 10% methanol/ethyl acetate to give the title compound: Rf=0.35 (silica gel, 10% methanol/ethyl acetate).
