Procedure

Combine 1-(2-methoxy-5-(1H-tetrazol-1-yl)benzoyl)-3-phenyl-3-(2-methanesulfonyloxyethyl)pyrrolidine (0.92 g, 1.95 mmol), 4-(1-(2-ethoxyethyl)-1H-benzimidazol-2-yl)[1,4]diazepane hydriodic acid salt (1.6 g, 2.9 mmol), and N,N-diisopropylethylamine (2.2 mL, 12.6 mmol) in acetonitrile (36 mL). Heat to reflux. After 22 hours, cool and partition the residue between a saturated aqueous sodium bicarbonate solution and ethyl acetate. Separate the organic layer and extract with a saturated aqueous sodium bicarbonate solution and then brine. Dry the organic layer over Na2SO4, filter, and evaporate in vacuo to give residue. Chromatograph the residue on silica gel eluting with dichloromethane/methanol/concentrated aqueous ammonia 90/10/0.1 to give the title compound.
