실험 절차

Combine 1-(t-butoxycarbonyl)-4-(1H-benzimidazol-2-yl)[1,4]diazepane (2.03 g, 6.41 mmol) and dimethylformamide (50 mL). Cool in an ice-bath. Add sodium hydride (0.28 g, 60% n in oil, 7.0 mmol). After 20 minutes, add 2-chloroethyl methyl ether (0.7 mL, 7.66 mmol). Heat to 85° C. After 18 hours, cool to ambient temperature and dilute with dichloromethane, and extract with water, a saturated aqueous sodium bicarbonate solution, and then brine. Dry the organic layer over MgSO4, filter, and evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with dichloromethane/methanol/concentrated ammonium hydroxide 95/5/0.05 to give 1-(t-butoxycarbonyl)-4-(1-(2-methoxyethyl)-1H-benzimidazol-2-yl)[1,4]diazepane.
