Triethylamine → 1-(2-Methoxy-5-(5-methylsulfonyl-1H-tetrazol-1-yl)benzoyl)-3-(2-(4-(1-(2-ethoxyethyl)-1H-benzimidazol-2-yl)[1,4]diazepan-1-yl)ethyl)-3-phenylpyrrolidine

Participants

Reaction Steps

Combine 1-(2-methoxy-5-(5-methylsulfonyl-1H-tetrazol-1-yl)benzoyl)-3-(2-methanesulfonyloxyethyl)-3-phenylpyrrolidine (0.44 g, 0.81 mmol), triethylamine (0.33 g, 3.23 mmol), and 4-(1-(2-ethoxyethyl)-1H-benzimidazol-2-yl)[1,4]diazepane hydriodic acid salt (0.44 g, 8.1 mmol) in acetonitrile (10 mL). Heat to reflux. After 12 hours, cool the reaction mixture, dilute with dichloromethane, and extract with water. Dry the organic layer over MgSO4, filter, and evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with 5% methanol/dichloromethane to give the title compound.
