実験手順
Ethyl 3-furancarboxylate (7.0 g) and hydrazine monohydrate (4.8 ml) in ethanol (10 ml) were heated at reflux while stirring for 6 hours. The solvent was evaporated under reduced pressure, and the thus-precipitated crystals were recrystallized from ethanol, thereby giving 3.2 g of the desire compound.
