실험 절차
Nitric acid (10 ml) was added slowly to a solution of 7-(3,5-dimethyl-4-isoxazolyl)-4-quinolinol (for a preparation see Intermediate 14 (28 g, 104 mmol) in propanoic acid (450 ml) at room temperature, followed by heating the reaction mixture to 100° C. for 1 h. After cooling with an ice bath, the precipitate was filtered off, washed with pentane to give the title compound as a yellow powder (27 g, 82%).
