Potassium Carbonate → [1-[2-[3-(3,4-Dichlorophenyl)-1-(3,4,5-trimethoxybenzoyl)pyrrolidin-3-yl]ethyl]piperidin-4-yl]-[1-[(4-fluorophenyl)methyl]benzimidazol-2-yl]methanone

Participants

Reaction Steps

Combine 1-(3,4,5-trimethoxy-benzoyl)-3-(3,4-dichloro-phenyl)-3-(2-methanesulfonyl-ethyl)-pyrrolidine (0.26 g, 0.488 mmol) and 4-[1-(4-fluoro-benzyl)-1 H-benzoimidazole-2-carbonyl]-piperidine (0.25 g, 0.73 mmol), and potassium carbonate (0.20 g, 1.46 mmol) in toluene/water (10/1)(5 mL). Heat to reflux. After 3 days, cool and evaporate in vacuo to obtain a residue. Partition the residue between dichloromethane and water. Dry the organic layer over Na2SO4, filter, and concentrate in vacuo to obtain a residue. Chromatograph the residue on silica gel eluting with 10/1 ethyl acetate/methanol to give the title compound: Rf=0.28 (silica gel, 10/1 ethyl acetate/methanol).
