Procedure
To a solution of 7-(3,5-dimethyl-4-isoxazolyl)-4-quinolinol (for a preparation see Intermediate 11, 8.5 g, 35 mmol) in propanoic acid (442 ml) was added nitric acid (7 ml) at room temperature, followed by heating the reaction mixture to 125° C. for 2 h. After cooling, the mixture was filtered, washed with isopropyl ether to give the title compound as a yellow solid (7.5 g, 75%). [APCI-MS] m/z: 283 [M−H]−, Rt 2.41 min.
