Participants

Reaction Steps

Combine 1-(3,4,5-trimethoxybenzoyl)-3-(3,4-difluorophenyl)-3-(2-methanesulfonyloxyethyl)pyrrolidine (0.48 g, 1.66 mmol) and (1-(2-ethoxyethyl)-1H-benzimidazol-2-yl)(piperidin-4-yl)amine (0.83 g, 1.66 mmol), and N,N-diisopropylethylamine (0.32 g, 2.49 mmol) in acetonitrile (10 mL). Heat to reflux. After 48 hours, cool and concentrate in vacuo to obtain a residue. Chromatograph the residue on silica gel eluting with 2% triethylamine/10% methanol/ethyl acetate to give the title compound: Rf=0.36 (silica gel, 2% triethylamine/10% methanol/ethyl acetate).
