実験手順

Combine 1-(5-(ethoxycarbonyl)fur-2-ylmethyl)-2-chloro-1H-benzimidazole (10 mmol), [1,4]diazepane (10 mmol), and 1,8-diazabicyclo[5.4.0]undec-7-ene (1.8 mL) in pyridine (20 mL). Heat to reflux. After 2 days, evaporate in vacuo to give a residue. Combine the residue and ethyl acetate. Extract with water and brine. Dry the the organic layer over Na2SO4, filter, and evaporate in vacuo to give 4-(1-(5-(ethoxycarbonyl)fur-2-ylmethyl)-1H-benzimidazol-2-yl)[1,4]diazepane.
