Reaction Steps

A mixture of the 4-(6-bromo-pyridin-3-yl)-2-oxo-3-butenoic acid sodium salt (900.0 mg, 3.2 mmol) in the form of a pale yellow solid, methyl iodide (400.0 mL, 6.47 mmol) in N,N-dimethylformamide (20.0 mL) was stirred at 75° C. for 3 hours. Distilled water was added to the reaction mixture, which was then extracted with ethyl acetate. The extract was washed with a saturated solution of sodium hydrogen carbonate and brine, dried on anhydrous magnesium sulfate, and then concentrated under reduced pressure to give 615.0 mg of the titled compound as a pale yellow solid.
