Diisopropylethylamine → 1-(t-butoxycarbonyl)-3-(2-(4-(1-(2-ethoxyethyl)-1H-benzimidazol-2-yl-amino)piperidin-1-yl)ethyl)-3-phenylpyrrolidine

Participants

Reaction Steps

Combine 1-(t-butoxycarbonyl)-3-phenyl-3-(2-methanesulfonyloxyethyl)pyrrolidine (25 mmol), (1-(2-ethoxyethyl)-1H-benzimidazol-2-yl)(piperidin-4-yl)amine (30 mmol), and N,N-diisopropylethylamine (18 mL, 101 mmol) in acetonitrile (300 mL). Heat to reflux. After 18 hours, evaporate in vacuo to give a residue. Chromatograph the residue on silica gel to give 1-(t-butoxycarbonyl)-3-(2-(4-(1-(2-ethoxyethyl)-1H-benzimidazol-2-yl-amino)piperidin-1-yl)ethyl)-3-phenylpyrrolidine.
