Combine 2-chloro-1-(5-ethyoxycarbonylfur-2-ylmethyl)-1H-benzimidazole (9.50 g, 31.2 mmol) and ethyl 4-aminopiperidine-1-carboxylate (5.4 g, 31 mmol), 1,8-diazabicyclo[5.4.0]undec-7-ene (5.6 mL, 37.4 mmol), and pyridine (90 mL). Heat to reflux. After 18 hours, cool to ambient temperature and evaporate in vacuo to give ethyl (1-(5-ethyoxycarbonylfur-2-ylmethyl)-1H-benzimidazol-2-yl)(1-ethoxycarbonylpiperidin-4-yl)amine.
