実験手順

Combine 1-t-butoxycarbonyl-4-(1-(4-fluorobenzyl)-1H-benzimidazol-2-yl)[1,4]diazepane (1.12 g, 2.64 mmol) and ethanol (15 mL). Add aqueous hydriodic acid (5 mL, 57%). Heat to reflux. After 1 hour, cool to ambient temperature and dilute with diethyl ether (250 mL) and stir to give a solid. Collect the solid by filtration, rinse with diethyl ether, and dry to give the title compound: Rf =0.16 (silica gel, 10% methanol/dichloromethane/0.01% concentrated aqueous ammonia.
