反应详情

(8-Bromo-[1,6]naphthyridin-2-yl)-carbamic acid tert-butyl ester (1 equiv.) is suspended in methanol (10 mL). Acetyl chloride (ca. 1 mL) is added over 1 minute. After the reaction mixture cools to ambient temperature, the solvent is brought briefly to reflux using a heat gun. The heat gun is applied twice more, at which point TLC (1:1 EtOAc:hexanes) indicated complete reaction. Concentration, followed by trituration twice with dry methanol affords the title compound as a white solid, LC/MS (M+H) 224.1.
