Embodiment 1
[0030] 2-(4-(3-ethynylaniline)-7-(2-methoxyethoxy)quinazoline-6-oxyl)ethyl-2-(4-benzoylphenyl)propionic acid synthesis
[0031]
[0032] step 1
[0033] Synthesis of ethyl 3-hydroxy-4-(2-methoxyethoxy)benzoate
[0034]
[0035] Dissolve 10.9g of ethyl 3,4-dihydroxybenzoate in 40ml of dry DMF (dimethylformamide), slowly add 3.6g of NaH under ice-cooling, and slowly drop in 8.34g of 2-bromoethyl after 10min under the protection of argon A solution of methyl ether and 100 mg KI dissolved in 10 ml of dry DMF was added dropwise within 3 hours, during which the reaction temperature was maintained at 0°C. After the dropwise addition, the reaction temperature was naturally raised to room temperature, and the reaction was carried out overnight, followed by TLC until the end of the reaction. The reaction solution was diluted with water, extracted with ethyl acetate, washed successively with saturated sodium chloride solution, and dried over anhydrous sodium sulfate. The crude ...
