Reaction Steps
The mixture that consists of 16.6 ml (173 mmol) of 2-bromopyridine, 21.6 ml of propargyl alcohol, 2.5 g of palladium-bis-triphenylphosphine-dichloride and 173 mg of copper(I) iodide is mixed with 510 ml of diethylamine and heated for 1.5 hours to 80° C. After filtration and removal of the solvent, the residue is purified by chromatography on fine silica gel with a gradient system that consists of n-hexane and ethyl acetate. 17.8 g (134 mmol, 77%) of the title compound is isolated as a colorless oil.
