実験手順

To a stirred solution of 5,6-dichloropyridin-3-amine (commercially available) and triethyl amine (3 eq) in CH2Cl2 (0.2 M) at 0° C. was added acetyl chloride (2 eq). After stirring at room temperature overnight the reaction mixture was concentrated under vacuum and the resulting crude residue was purified by chromatography (silica gel, 20-50% EtOAc in hexanes) to afford N-(5,6-dichloropyridin-3-yl)acetamide.
