Reaction Conditions

Reaction Steps

Isonicotinic acid ethyl ester (5 g, 33 mmol), was dissolved in ethanol (40 mL). Methyl iodide (4.13 mL, 66.1 mmol) was added and the clear solution was stirred overnight at 60° C. The resulting mixture was evaporated to yield a red/orange solid, which was determined by 1H NMR and thin-layer chromatography (TLC) to be the title product in quantitative yield. The crude mixture was used directly in the following reaction.
