Embodiment 1
[0155] Example 1: 4-(3-chloro-4-fluoroanilino)-6-methoxy-7-[[3-[(5-dimethylamino)methylfuran-2-]methylthio] Propoxy]quinazoline oxalate
[0156]Step A: Preparation of methyl 3-methoxy-4-(3-chloropropoxy)benzoate
[0157] In 150 mL of dimethylformamide (DMF), add 9.1 g (0.05 mol) of methyl 3-methoxy-4-hydroxybenzoate, 15.8 g (0.1 mol) of 1,3-bromochloropropane, anhydrous carbonic acid Potassium 10.4g (0.075mol), stirred at 70-80°C for 6h. After the reaction was completed, the reaction solution was poured into ice water, extracted with dichloromethane, the organic phases were combined, washed with water, dried over anhydrous magnesium sulfate, evaporated to remove the solvent, and dried to obtain 12.3 g of the product (yield: 95.3%).
[0158] Step B: Preparation of methyl 2-nitro-4-(3-chloropropoxy)-5-methoxybenzoate
[0159] 12.3 g (0.048 mol) of methyl 3-methoxy-4-(3-chloropropoxy)benzoate was added to 100 mL of chloroform, and stirred to dissolve. Cool to about 10°C, slow...
Embodiment 2-39
[0173] According to the method of Example 1, using methyl 3-methoxy-4-hydroxybenzoate and 1,3-bromochloropropane or 1,2-bromochloroethane as starting materials, first prepare 4-chloro- 6-methoxy-7-(3-chloroalkoxy) quinazoline, then with suitable amine substitution reaction, then with furanmethylthiol substitution reaction, and then carry out Mannich reaction with suitable aliphatic amine, respectively Compounds of Examples 2-39 were obtained:
