Reaction Steps

0.196 mL of a Red-Al solution (65% in toluene) was added dropwise at 0° C. to a solution of 70 mg of rac-(1R*,2R*,4R*)-N-[3-(1H-benzoimidazol-2-yl)-propyl]-2-(2-hydroxy-5-thiophen-2-yl-bicyclo[2.2.2]oct-5-en-2-yl)-N-methyl-acetamide in toluene (0.8 mL). The reaction mixture was stirred for 30 min at 0° C. then the temperature was allowed to increase to rt for 3.5 h. The mixture was carefully poured onto a mixture of 1M-NaOH (6.1 mL) and ice. The mixture was stirred for 5 min until rt and extracted with toluene. The aq. phase was extracted with toluene. The combined toluene phase was washed with 1M-NaOH and brine, dried over anh. Na2SO4 and concentrated in vacuo to yield 54 mg of rac-(1R*,2R*,4R*)-2-(2-{[3-(1H-benzoimidazol-2-yl)-propyl]-methyl-amino}-ethyl)-5-thiophen-2-yl-bicyclo[2.2.2]oct-5-en-2-ol as a colorless solid.
