Versuchsvorschrift

Combine 1-(3,5-dimethoxy-4-methanesulfonyloxybenzoyl)-3-(2-(4-(1-(2-ethoxyethyl)-1H-benzimidazol-2-yl)[1,4]diazepan-1-yl)ethyl)-3-phenylpyrrolidine (0.5 g, 0.5 mmol) and methanol (4 mL). Add potassium carbonate (0.5 g). After 18 hours, add a 1 M aqueous sodium hydroxide solution (1 mL) and extract with dichloromethane. Dry the organic layer over Na2SO4, filter, and concentrate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with dichloromethane/methanol/concentrated aqueous ammonia 6/1/0.1 to give a residue. Combine the residue and dichloromethane (4 mL). Add a solution of hydrochloric acid in dioxane (0.12 mL, 4 M, 0.48 mmol). Warm to ambient temperature. After 1 hour, evaporate in vacuo to give a residue. Triturate with diethyl ether to give a solid. After 1 hour, collect the solid by filtration and dry to give the title compound.
