Reaktionsschritte

To a solution of methyl 5-methyl-3-furancarboxylate (0.314 mL, 2.5 mmol, commercially available from e.g. Sigma-Aldrich, Fluorochem or Alfa Aesar) in ethanol (20 mL) was added hydrazine monohydrate (0.093 mL, 3.00 mmol) and the solution was stirred under argon and reflux for 18 hours. Analysis by LCMS and TLC showed starting material to still be present, thus more hydrazine monohydrate (0.275 mL, 8.75 mmol) was added and the solution was further stirred under argon and reflux for 18 hours. The solvent was then evaporated in vacuo to yield the product in 0.341 g.
