실험 절차
A mixture of 1.0 g. of 6-(3,5-dibromo-2-hydroxy-4-methylphenyl)-3-(2H)pyridazinone and 2 ml. of acetic anhydride in 10 ml. of benzene was heated under reflux for 3 hours. After cooling, the so separated crystalline substance was recovered by filtration and dried to give 0.8 g. of the desired product as yellow needles of m.p. 220° C. (Yield 71.5%).
