실험 절차

7-Fluoro-1,5-naphthyridin-2(1H)-one (2.152 g, 13.122 mmol) was suspended in dry DMF (40 ml) under argon at 0° C., and the stirred suspension was treated with sodium hydride (1.155 g of a 60% w:w dispersion in oil, 2.2 eq.) added in portions. The suspension was allowed to warm to rt. After stirring for 30 mins at rt, the mixture was treated with allyl iodide (2.67 ml, 2.2 eq) and then stirred for a further 30 min before addition of water (100 ml). The mixture was then extracted with DCM (3×200 ml). The organic extracts were combined, dried over anhydrous magnesium sulphate, filtered and evaporated to give a residue which was purified by column chromatography on silica with a 0-10% methanol in DCM gradient to give the desired product as a light brown solid (1.683 g, 63%).
