Nitric Acid → HCID 178487724, compound

Participants

Reaction Steps

A mixture of 7-methoxyquinolin-4-ol (5.0 g, 28.5 mmol) and propionic acid (50 mL) was heated to reflux. Nitric acid (3.2 mL of 70% , 50 mmol) was added dropwise over a period of 15 minutes. The reaction mixture was refluxed for 2 hrs and then allowed to cool to ambient temperature. The resulting precipitate was isolated by filtration, washed with cold ethanol followed by hexanes and then dried to provide 3.9 g of 7-methoxy-3-nitroquinolin-4-ol as a gray solid.
