실험 절차

To a solution of 150 mg of rac-(1R*,2R*,4R*)-2-(2-{[3-(1H-benzoimidazol-2-yl)-propyl]-methyl-amino}-ethyl)-5-phenyl-bicyclo[2.2.2]oct-5-en-2-ol and 0.176 mL of NEt3 in 4 mL DCM 0.1 mL of isobutyrylchloride was added at 0° C. The yellow reaction mixture was stirred for 3 h at rt and then quenched with sat. aq. NaHCO3. The product was extracted with DCM, the organic phase was evaporated to dryness. The residue was dissolved in EtOAc, silica gel and a few drops of MeOH were added and the mixture was stirred vigorously for 5 h. The mixture was filtered, the filtrate evaporated and the residue purified by CC with EtOAc-MeOH (3:1) to yield 86 mg of pure 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 as colorless foam.
