반응 단계

Combine 1-(3,4,5-trimethoxybenzyl)-3-(4-fluorophenylmethyl)-3-(3-methanesulfonyloxypropyl)-2-oxopyrrolidine (0.35 g, 0.68 mmol), (1-(ethoxycarbonylmethyl)-1H-benzimidazol-2-yl)(piperidin-4-yl)amine hydriodic acid salt (0.38 g, 0.68 mmol), and triethylamine (0.276 g, 2.72 mmol) in acetonitrile (15 mL). Heat to reflux. After 12 hours, cool the reaction mixture, dilute with dichloromethane, and extract with brine. Dry the organic layer over Na2SO4, filter, and concentrate in vacuo to obtain a residue. Chromatograph the residue on silica gel eluting with 5% methanol/0.5% concentrate aqueous ammonium hydroxide/dichloromethane to give the title compound.
