Reaction Steps

86 mg of rac-isobutyric acid (1R*,2R*,4R*)-2-(2-{[3-(1H-benzoimidazol-2-yl)-propyl]-methyl-amino}-ethyl)-5-phenyl-bicyclo[2.2.2]oct-5-en-2-yl ester were dissolved in 2 mL EtOAc, the solution was cooled with an ice bath and 1 mL of 3M HCl in EtOAC was added. The reaction mixture was evaporated to dryness without heating to give the desired rac-isobutyric acid (1R*,2R*,4R*)-2-(2-{[3-(1H-benzoimidazol-2-yl)-propyl]-methyl-amino}-ethyl)-5-phenyl-bicyclo[2.2.2]oct-5-en-2-yl ester dihydrochloride.
