Reaction Steps
Under a nitrogen atmosphere, to a solution of ethyl 3-cyclopropyl-3-(2-methoxypyridin-4-yl)propanoate (4.17 g) in DMF (10 mL) was added pyridinium chloride (19.3 g), and the mixture was stirred at 130° C. for 15 min. Ethyl acetate was added to the reaction mixture at 0° C., and the resulting white precipitate was filtered off. The solvent in the filtrate was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (methanol/ethyl acetate) to give the title compound (3.61 g) as a yellow oil.
