Yield:168551-49-3 84%

Reaction Conditions:

with triethyl phosphite in dichloromethane at 20; for 4 h;Reagent/catalyst;

Steps:

1-2

In a 25 mL round bottom flask, 5.0 mL of dichloromethane, 0.5 mmol of o-phthalaldehyde, 0.55 mmol of phenol and 0.55 mmol of triethyl phosphite were sequentially added, and the resulting reaction mixture was stirred at room temperature for 4 hours. After the reaction is completed, the solvent is removed by rotary evaporation, and the crude product is purified by 200-300 mesh silica gel column chromatography. The eluent is a mixed solvent of petroleum ether and ethyl acetate with a boiling range of 60-90 degrees Celsius, and the volume ratio is 40:l-30 :1 to obtain a colorless oily liquid with a yield of 84%. The preparation amount of the benzyl aryl ether target compound I and the volume of the reaction vessel can be expanded or reduced according to the corresponding ratio. The chemical structure and physical and chemical parameters of the target compound I are shown in Table 1.
