実験手順

Commercial 6-fluoropyridin-3-amine (500 mg, 4.46 mmol) was dissolved in 20 mL dry NMP. To it were added pyrazole (910 mg, 13.4 mmol) and cesium carbonate (4.4 g, 13.4 mmol). The mixture was stirred in a sealed tube at 120° C. for over the weekend (3 nights). The mixture was diluted with chloroform, washed with brine (3 times), dried, concentrated and subjected to flash column (0 to 30% EtOAc in DCM) to isolate 6-(1H-pyrazol-1-yl)pyridin-3-amine (120 mg, 17% yield).
