실험 절차

A mixture of 50 mg of 2-benzyl-6-[(3R,4S)-3-hydroxy-4-fluoropyrrolidine-1-yl]-3-iodopyridine, 21 mg of (3R)-3-ethynyl-3-quinuclidinol, 15 mg of tetrakis(triphenylphosphine)palladium(0), 1 mg of cuprous iodide, 53 μl of triethylamine and 3.0 ml of N,N-dimethylformamide was heated under stirring for 3 hours at 75° C. in a nitrogen atmosphere. The reaction solution was poured into an aqueous dilute ammonia, was then extracted with ethyl acetate. Then, the organic phase was washed with brine and the solvent was removed. The residue was subjected to NH-silica gel (Fuji Silicia) column chromatography and eluted with hexane/ethyl acetate (1:1) and then with ethyl acetate/methanol (15:1), to give 37 mg of the target compound.
