Procedure

Combine 1-(3,5-dimethoxy-4-methanesulfonyloxybenzoyl)-3-phenyl-3-(2-methanesulfonyloxyethyl)pyrrolidine (0.77 g, 1.46 mmol), 4-(1-(2-ethoxyethyl)-1H-benzimidazol-2-yl)[1,4]diazepane hydriodic acid salt (1.0 g, 1.8 mmol), and N,N-diisopropylethylamine (0.76 g, 4.4 mmol) in acetonitrile (36 mL). Heat to reflux. After 16 hours, cool and evaporate in vacuo to give residue. Chromatograph the residue on silica gel eluting with dichloromethane/methanol/concentrated aqueous ammonia 6/1/0.1 to give the title compound.
