反応手順
A mixture of 3-fluoroiodobenzene (8.88 g), 4-methyl-1-(2-propynyl)piperidine (6.80 g), palladium acetate (0.045 g), tri-o-toloylphosphine (0.24 g) and copper(I) iodide (0.1 g) in dry diethylamine (50 ml) was heated under reflux for 5 hours. The solvent was removed under reduced pressure and the residue was taken up in diethyl ether and washed with water. The organic phase was dried over magnesium sulfate and the solvent was removed under reduced pressure. Distillation of the residue under reduced pressure gave an oil (5.20 g) of boiling point 105° C./0.07 mm Hg.
