Embodiment 1
[0135] Embodiment 1 Preparation of compounds with structures shown in formula II and malate thereof
[0136] Step 1: Preparation of a compound having a structure shown in formula XII
[0137] Weigh the compound (1.5 g, 6.7 mmol) having the structure shown in Formula XVIII and add it into a stuffy jar, then add 15 mL of acetic acid and 15 mL of 40% hydrobromic acid in sequence, and raise the temperature to 140° C. overnight (about 15 hours). LC-MS detected that there was no starting material, and at the same time, part of 6,7-dimethyloxy-4-bromoquinoline was generated. After directly evaporating the reaction liquid, add 25mL of water to make a slurry, then use a small amount of ammonia water to adjust the pH value to about 10, and make a slurry for 1 hour, then filter with suction to obtain a solid, use absolute ethanol (20mL) to azeotrope three times with water, and then use an oil pump Pump to constant weight. 1.3 g of white solid were obtained. Carry out LC-MS detection, ...
