Acetic Acid → HCID 66920377, compound

Participants

Reaction Steps

To a solution of 2-pyridylhydrazine (10.0 g, 91.6 mmol) in water (30 mL) was added acetic acid (8.7 mL). This mixture was then added to a solution of pyruvaldehyde (16.5 g, 14.9 mL, 91.6 mmol) in water (400 mL). The mixture was stirred at room temperature for 3 days. The mixture was neutralized with NaHCO3 (solid) whereupon a yellow precipitate forms. The solid was isolated by filtration and then washed with water (30 mL). The solids were dried under high vacuum to afford 2-oxopropanal pyridin-2-ylhydrazone as a yellow solid (6.12 g, 41%).
