[0125] The preparation method of the compound represented by the general formula (I) of the present invention and its pharmaceutically acceptable salt, or prodrug, solvate, polymorph, stereoisomer, or tautomer, etc., comprises the following Preparation:
[0126] Method 1: The reaction raw material IA is reacted with aromatic amines, phenols or thiophenols under acid catalysis (such as hydrochloric acid, pyridine hydrochloride, sulfuric acid, etc.) or base catalysis (such as potassium carbonate, sodium bicarbonate, triethylamine, etc.) reaction to generate intermediate IB; intermediate IB is then subjected to substitution reaction with halogenated hydrocarbon (or sulfonate of alcohol, etc.), or Mitsunobu reaction with alcohol to obtain intermediate IC; intermediate IC and various amines (ring A) A substitution reaction was carried out to obtain the target compound ID. Wherein n is an integer such as 1, 2, 3; LG is a leaving group such as halogen, sulfonate, acetate; A, Ar and ...

[0140]
[0141] The first step: 4-chloro-7-(3-chloro-propoxy)-6-methoxy-quinoline-3-cyanide
[0142] Anhydrous potassium carbonate (10.6g, 6eq) was added to a DMF solution (30mL) of 4-chloro-7-hydroxyl-6-methoxyquinoline-3-cyanide (3g, 12.7mmol) under ice-cooling, and stirred for half After 1 hour, 1-chloro-3-iodopropane (13 g, 63.9 mmol) was added to the above suspension and stirred overnight at room temperature. The reaction solution was diluted with water (500mL), extracted with dichloromethane (250mLX2), the combined organic phases were washed with water and saturated brine, dried over anhydrous sodium sulfate, filtered, concentrated under reduced pressure, and purified by silica gel column chromatography to obtain 4-chloro- 7-(3-Chloro-propoxy)-6-methoxy-quinoline-3-cyanide (yellow solid, 3.1g), yi...
