실험 절차

2-(4-fluorobenzoyl)benzoic acid (5 g; 20.47 mmol) is suspended in ethanol (100 ml). Hydrazine (3 M in ethanol; 60 mmol) is added, and the mixture is stirred at room temperature for 4 days. A white solid precipitates, is filtered off and is washed with ethanol (20 ml). Yield: 3.20 g of 4-fluorophenylphthalazine-1-one.
