実験手順

To a solution of 6-bromopyridin-2-amine (1 g, 5.78 mmol) in acetonitrile (10 mL) was added N-chlorosuccinimide (0.849 g, 6.36 mmol) and the mixture was heated at 80° C. for 12 hours. The mixture was filtered through diatomaceous earth and concentrated and the residue was dissolved in ethyl acetate and washed with water and brine. Drying over anhydrous sodium sulfate, filtration, concentration and purification by column chromatography (silica gel, 30% ethyl acetate in hexane) afforded the title compound. LCMS: 209.1 (M+2)+.
