Reaction Steps
Sulfuric acid (400 ml) was added slowly to water (400 ml). After cooling to 5° C., 2-fluoro-phenylhydrazine hydrochloride (123 g, 757 mmol) was added resulting in a brown suspension. Then a solution of oxalacetic acid (100 g, 757 mmol) in water (400 ml) was added slowly during a period of 25 min. After 2 h the conversion was complete and the solid was filtered. After washing with water the solid was dried. The product was obtained as light brown solid (151 g, 90%).
