Sodium Iodide → 1-(2-methoxy-5-(1H-tetrazol-1-yl)benzoyl)-3-(2-(4-(1-(2-(trifluoromethoxy)ethyl)-1H-benzimidazol-2-yl-amino)piperidin-1-yl)ethyl)-3-phenylpyrrolidine

Participants

Reaction Steps

Combine 1-(2-methoxy-5-(1H-tetrazol-1-yl)benzoyl)-3-phenyl-3-(2-methanesulfonyloxyethyl)pyrrolidine (prepared from (−)-3-(2-hydroxyethyl)-3-phenylpyrrolidine (R,R)-di-p-anisoyltartaric acid salt) (0.86 g, 1.83 mmol), (1-(2-(trifluoromethoxy)ethyl)-1H-benzimidazol-2-yl)(piperidin-4-yl)amine hydrochlorici acid salt (1.66 mmol), triethylamine (1.0 mL, 7.2 mmol), and sodium iodide (0.31 g) in acetonitrile (24 mL). Heat to reflux. After 48 hours, evaporate in vacuo to give a residue. Partition the residue between dichloromethane and a saturated aqueous sodium, bicarbonate solution. Separate the layers and extract the organic layer with a saturated aqueous sodium bicarbonate solution and then brine. Dry the organic layer over Na2SO4, filter, and evaporate in vacuo to give the title compound.
