実験手順

A solution of methyl 2-methylnicotinate (4.9 g, 32.1 mmol) and 3-bromo-2-butanone (4.8 g, 32.1 mmol) in acetone (40 ml) were warmed to reflux for 3 d. Cooled to RT and partially purified the remaining residue via column chromatography (silica gel, 5-10% EtOAc/hexanes). The product-containing fractions were combined and concentrated to give the desired product.
