Versuchsvorschrift

Combine 1-(3,4,5-trimethoxybenzyl)-3-(4-fluorophenylmethyl)-3-(3-methanesulfonyloxypropyl)-2-oxopyrrolidine (0.43 g, 1.50 mmol), (1-(2-ethoxyethyl)-1H-benzimidazol-2-yl)(piperidin-4-yl)amine (0.74 g, 1.46 mmol), and N,N-diisopropylethylamine (0.39 g, 3.0 mmol) in acetonitrile (10 mL). Heat to reflux. After 12 hours, dilute the reaction mixture with ethyl acetate and extract twice with water. Dry the organic layer over Na2SO4, filter, and evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with 10% methanol/ethyl acetate/2% triethylamine. Combine the product containing fractions and evaporate in vacuo to give a residue. Combine the residue and dichloromethane and extract with brine. Dry the organic layer over Na2SO4, filter, and evaporate in vacuo to give the title compound.
