Reaction Steps

tert-Butyl (2-iodopyridin-4-yl)carbamate (2.41 g, 7.5 mmol), copper(I) iodide (50 mg, 0.3 mmol) and bis(triphenylphosphine)palladium(II) chloride (200 mg, 0.3 mmol) were stirred in tetrahydrofuran (22 mL) with triethylamine (1.1 mL, 8.1 mmol) under N2 at rt. 3-Ethynylaniline (0.75 mL, 7.2 mmol) was added and the mixture was stirred at rt for 40 hours. The reaction mixture was diluted with water. After removal of the solvent, the aqueous residue was extracted with EtOAc three times, followed by drying, filtration, and concentration to give the desired product as a brown solid (1.97 g, 89%). LCMS for C18H20N3O2 (M+H)+: m/z=310.1.
