Procedure

Alternatively, combine 4-(1-(5-(ethoxycarbonyl)fur-2-ylmethyl)-1H-benzimidazol-2-yl)[1,4]diazepane (1.0 g, 2.7 mmol) and tetrahydrofuran (10 mL). Add a solution of lithium aluminum hydride in tetrahydrofuran (2.7 mL, 1 M, 2.7 mmol). After 18 hour, quench by slow portionwise addition of Glauber's salt (Na2SO4•10 H2O) until gas evolution ceases. Add dichloromethane (20 mL) and celite and stir. Filter and evaporate in vacuo to give the title compound.
