7-(3,5-dimethyl-4-isoxazolyl)-4-hydroxy-3-quinolinecarboxylate (for a preparation see Intermediate 9, 10 g, 35.21 mmol) was suspended by small portions to boiling diphenyl ether (200 ml) and allowed to reflux for 2 h. The reaction mixture was poured into hexane (500 ml) at 0° C., the precipitate was filtered and washed several times with hexane to give the title compound as a white solid (6.8 g, 86%).
