example 1
[0020] Example 1, the preparation of formula I compound
[0021] (1) Preparation of Naphthalene Acetyl Chloride
[0022]
[0023] Add 18.6g (0.1mol) of naphthalene acetic acid and 100mL of toluene to a 250mL three-necked flask respectively, and dropwise add a solution composed of 17.9g (0.15mol) of thionyl chloride and 30mL of toluene. The solvent dichloromethane and thionyl chloride were distilled off to obtain 19.4 g of light yellow oily liquid with a yield of 94.6%.
[0024] (2) preparation of formula II compound
[0025]
[0026] Add 19.8g (0.1mol) of naphthalene dicarboxylic anhydride and 6.1g (0.1mol) of ethanolamine to a 250mL three-necked flask respectively, and 100mL of water as a solvent, heat to reflux, after the reaction is complete, cool the light yellow crystalline solid filtered by suction, and dry , to obtain 23.4g, yield 97.1%.
[0027] (3) preparation of formula I compound
