Reaction Steps
A mixture of 2-iodo-6-methylpyridine-3-ol (20 g, 85 mmol), CuI (2.1 g, 11 mmol), trimethylsilyl acetylene (23.4 g, 238 mmol), and bis(triphenylphosphine)palladium(II)chloride (5.37 g, 7.65 mmol) in Et3N (380 mL) was heated to reflux for 20 hr. The mixture was cooled and diluted with ether and filtered through celite. The filtrate was concentrated in vacuo and the residue was chromatographed on silica gel (eluted with 10% EtOAc in hexane) to give 15 g (86%) of the title compound.
