The reaction was stirred at 80 0C. The starting material didn't dissolve well in TetaF. After 3.5 hours, mainly staring material was observed. DMF (18 mL) was added and the starting material went into solution. The reaction was heated at 80 0C for 45 minutes. The desired mass was observed by LCMS. The reaction was filtered using ethyl acetate and the solvent was evaporated under reduced pressure. The crude product was separated by column chromatography on silica gel (0-100percent ethyl acetate in hexane) to yield methyl 2-(5-bromo-3-cyano-2-oxopyridin-l(2H)-yl)acetate as a yellow solid (1.42 g, 74percent).
