Versuchsvorschrift

To a room temperature solution of (E)-methyl 3-(3-aminopyridin-2-yl)acrylate (3.63 g, 20.37 mmol) in MeOH (40 mL) was added sodium methoxide, 25 wt % solution in methanol (20.00 mL, 90 mmol). The reaction was heated at 60° C. for 6 h, the mixture was cooled to room temperature and the solvent was removed in vacuo to give tan solid. ESI-MS 147.0 [M+1].
