Reaction Steps

To an ice-cold solution of 2-amino-5-bromopyridin-3-ol (1 g, 5.29 mmol) in DMF (10 mL) was added KF (0.77 g, 13.23 mmol) followed by addition of diethyl 2-bromo-2-methylmalonate (1 mL, 5.29 mmol) and the mixture heated up to 60° C. for 4 h. After completion (by TLC), the reaction was cooled, quenched with water and extracted with EtOAc (3×100 mL). The combined organics were washed with brine, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to obtain the desired product as an off-white solid (1 g, 60%).
