YieldReaction ConditionsOperation in experiment
51% With triethylamine;copper(l) iodide; In tetrahydrofuran; at 0 - 20℃; for 2h;Inert atmosphere; The bromopyrazine (3 g, 11.87 mmol) was dissolved in THF (60 mL) and the resultant solution was purged with argon. Triethylamine (1.44 g, 14.24 mmol), CuI (180 mg) and PdCl-(PPh3)2 (83 mg, 0.118 mmol) were added. The reaction mixture was cooled to 0 C. Trimethylsilylacetylene (1.28 g, 13.05 mmol) was slowly added and the reaction was left to warm up to rt for 2 h. The reaction mixture was diluted with water and filtered through celite. The crude mixture was extracted three times with EtOAc. The organic layer was separated, dried (Na2SO4), filtered and concentrated. The crude residue was purified by SiO2 chromatography eluting with an EtOAc/hexane gradient to afford 3.3 g (51%) of alkyne as a yellow solid.
