실험 절차

50 mg of rac-(1R*,2R*,4R*)-2-(2-methylamino-ethyl)-5-phenyl-bicyclo[2.2.2]oct-5-en-2-ol were dissolved in DCM/AcOH. 46 mg of 3-methoxy-2-methoxymethyl-2-methyl-N-(3-oxo-propyl)-propionamide and 50 mg of sodium cyanoborohydride were added. The reaction mixture was stirred for 3 days at room temperature, quenched with sat.-NaHCO3 and extracted with DCM. The organic phase was washed with brine, dried over anh. Na2SO4 and concentrated in vacuo. The resulting crude material was purified by CC using EtOAc/MeOH/NEt3 90/10/1 as eluant to yield 49 mg of rac-N-(3-{[2-((1R*,2R*,4R*)-2-hydroxy-5-phenyl-bicyclo[2.2.2]oct-5-en-2-yl)-ethyl]-methyl-amino}-propyl)-3-methoxy-2-methoxymethyl-2-methyl-propionamide as a yellow oil.
