Reaction Steps
A mixture of 2-iodo-3-hydroxy-pyridine (0.44 g, 2 mmol), (2-oxo-1-prop-2-ynyl-pyrrolidin-3-(S)-yl)-carbamic acid tert-butyl ester (0.6 g, 2.5 mmol), bis(triphenylphosphine)-palladium(II) chloride (Pd(PPh3)2Cl2) (50 mg), copper iodide (25 mg) and triethylamine (3 mL) in 3 mL of acetonitrile is heated in a sealed tube at 120° C. for 2 hours. After cooling, the reaction mixture is diluted with water and EtOAc and the layers are separated. The aqueous layer is extracted with EtOAc. The combined organic layers are washed with water and saturated NaCl solution, then dried over MgSO4, filtered and concentrated. The crude product is purified by column chromatography eluting with a gradient of 25% EtOAc/CH2Cl2 to 90% EtOAc/CFH2Cl2 to yield the title compound as a white solid.
