Procedure

Combine 1-(t-butoxycarbonyl)-4-(1-(2-(1H-imidazol-1-yl)ethyl)-1H-benzimidazol-2-yl)[1,4]diazepane (0.22 g, 0.54 mmol), 57% hydriodic acid (0.25 mL, 1.13 mmol), methanol (10 mL) and heat to reflux. After 20 hours, cool the reaction mixture and evaporate in vacuo to give a residue. Triturate the residue with diethyl ether to give a solid. Repeatedly, decant and add diethyl ether before collecting the solid by filtration, rinse with diethyl ether, and dry in vacuo to give the title compound.
