실험 절차
A precipitate is obtained when a mixture of methyl anthraniliate (4.78 g, 31.6 mmol), 6-chloropyridazine-3-carboxylic acid (5.0 g, 31.6 mmol) and 50 ml of acetic acid is heated at reflux for 21 hrs; m.p. 246°-50° C. This crude material is recyrstallized from pyridine giving the anlytical sample, m.p. 239°-43° C. (dec.).
