Reaction Steps

To a solution of ethyl 5-(2-acetamido-5-methylpyridin-4-yl)-3-furoate (20.0 g, 69.9 mmol) in DMF (90 mL) was added NBS (29.6 g, 168.1 mmol). The reaction mixture was allowed to stir at 80° C. overnight and then concentrated. The residue was washed with EtOH and filtered to give ethyl 5-(2-acetamido-5-methylpyridin-4-yl)-2-bromo-3-furoate (20 g, 60%).
