実験手順

2-Chloro-5-iodo-N-(tricyclo[3.3.1.13,7]dec-1-ylmethyl)-benzamide (prepared as described in WO 99/29661) (7.74 g), tri-n-butylallyltin (5.99 g), dichlorobis(triphenylphosphine)palladium(II) (1.24 g), triphenylphosphine (1.86 g), lithium chloride (6.11 g) and N,N-dimethylformamide. (260 mL) were heated together under nitrogen from 110° C. to 130° C. over 20 minutes, and then at 130° C. for 25 minutes. The mixture was then cooled, poured into brine (500 mL), extracted into ethyl acetate (3×250 mL), dried over anhydrous magnesium sulfate, filtered and concentrated to give an oil. The crude mixture was purified by column chromatography eluting with 9:1 isohexane/ethyl acetate to give the sub-titled compound (5.23 g).
