실험 절차

A mixture of (2,5-dioxo-2,5-dihydro-3-furanyl)acetic acid (9 g) and hydrazine sulphate (7.2 g) in water was heated to reflux for 4 hours then allowed to cool to ambient temperature. The precipitate was filtered, washing with water then acetone. Drying in vacuo afforded a white solid (8.04 g, 82%).
