preparation Embodiment 1

[0164] Preparation Example 1 Preparation of intermediate [3-(4-methylpiperazin-1-yl)-7-trifluoromethyl-5-hydroxyquinoline]

[0165]

[0166] Preparation of 7-trifluoromethyl-5-nitroquinoline: 3-nitro 5-aminobenzotrifluoride (7.5g), glycerol (12.3g), and arsenic pentoxide (6.8g) were added to the reaction flask After stirring until the mixture is uniform, slowly add concentrated sulfuric acid (8g), first react at 130°C for one hour, then raise the temperature to 180°C for four hours. After the reaction is completed, the reaction solution is cooled to room temperature, and then adjusted to be alkaline with 4mol / L sodium hydroxide solution, the solid is filtered out, the solid is dissolved in ethanol, decolorized by activated carbon, the solvent is evaporated, and 7- Trifluoromethyl-5-nitroquinoline (1.7 g, 15%). 1 H-NMR (300MHz, CDCl 3 ): δ9.14(dd, 1H, J1=1.5Hz, J2=4.2Hz), 9.03(d, 1H, J=9.0Hz), 8.71(s, 1H), 8.54(d, 1H, J=1.5Hz ), 7.77 (dd, 1H, J1=9.0Hz, J2=4.2Hz).
