Reaction Steps

A mixture of dimethyl (5-acetyl-3-chloropyridin-2-yl)malonate (2.18 g, 7.63 mmol) and 48% HBr aq. (10.0 mL) was stirred at 120° C. for 1.5 hours. The mixture was neutralized by the addition of sat.NaHCO3 aq. The mixture was extracted with EtOAc. The organic layer was washed with brine, dried over Na2SO4, concentrated to give the title compound (810 mg, 63%) as a slight yellow solid. 1H NMR (300 MHz, CDCl3) δ 2.62 (3H, s), 2.71 (6H, s), 8.17 (1H, s), 8.92 (1H, s).
