Versuchsvorschrift

Sodium methoxide (1.21 g) was added to a solution of 2-(bromomethyl)acrylic acid methyl ester (1.0 mL) in methanol (10 mL), and the mixture was heated under reflux for 26 hours. The reaction mixture was cooled, and was diluted with diethyl ether. The precipitate was filtered off, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate hexane=1:4), to thereby give the title compound (726 mg).
