Reaction Steps

Bis(triphenylphosphine)palladiumdichloride (0.082 g, 0.118 mmol) was added to a solution of 6-chloro-2-methoxy-3-nitropyridine (0.554 g, 2.94 mmol), trimethylsilylacetylene (0.623 mL, 4.41 mmol), triethylamine (1.843 mL, 13.22 mmol) and copper iodide (0.022 g, 0.118 mmol) in DMF (10.1 mL). The reaction mixture was heated at 80° C. for 1 hour. The reaction mixture was diluted with water and the aqueous layer was extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo. The crude residue was purified by Biotage silica gel column chromatography eluting with cyclohexane/EtOAc (99/1) to afford the title compound as a yellow oil (370 mg, 50%).
