Versuchsvorschrift

To a 28% sodium methoxide/methanol solution (4.24 g) in methanol (35 mL) was added methyl 2-(bromomethyl)acrylate (1.79 g) in methanol (10 mL). The mixture was stirred at room temperature for 2 hours and was heated to reflux for 3 hours. The reaction mixture was poured into 2N hydrochloric acid-ice, then extracted with ethyl acetate. The obtained organic layer was washed with brine, dried and concentrated to give the title compound (1.33 g) having the following physical data.
