Some common heterocyclic compound, 15964-79-1, name is Methyl 2-(3,4-dimethoxyphenyl)acetate, molecular formula is C11H14O4, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 15964-79-1
To a solution of 315 mg (1.5 mmol) of 3,4-dimethoxyphenyl methyl acetate in 5 ml of anhydrous CHCl3, add at 0 C. and under an inert atmosphere 452 mul (3 mmol) of 1-naphthoyl chloride. Add dropwise 351 mul of SnCl4. Allow to return to room temperature. [0299] After 6 hours at room temperature, evaporate to dryness. Add 10 ml of MeOH. Stir at room temperature for 30 minutes. Evaporate to dryness. Add 7 ml of iced H2O. Allow to crystallize at 0 C. for 1 hour. Filter. Wash twice with 1 ml of H2O. Yield: 37%. The product is used as is for the subsequent reactions.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 15964-79-1, its application will become more common.
