Combine 1-(3,4,5-trimethoxybenzoyl)-3-(3,4-difluorophenyl)-3-(2-methanesulfonyloxyethyl)pyrrolidine (0.37 g, 1.6 mmol), 4-(1-(2-ethoxyethyl)-1H-benzimidazol-2-yl)[1,4]diazepane hydriodic acid salt (0.43 g, 0.8 mmol), and N,N-diisopropylethylamine (0.41 g, 3.2 mmol) in acetonitrile (10 mL). Heat to reflux. After 12 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).
