Application of 1777-82-8, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 1777-82-8 as follows.
The reactants used were 2,4-dichlorobenzyl alcohol (i.e., R1 in the formula (I) was ortho, with two Cl) 1.0 mmol(177.0 mg), the experimental method and procedure were the same as in Example 1, ammonia water (1.8 mol / L) 5.0 mL, and the amount of catalyst cuprous bromide was5 mol% (7.2 mg), TEMPO was used in an amount of 5 mol% (7.8 mg), the reaction temperature was 80 C, the reaction time was 24 h, and the crude productPurification by column chromatography (petroleum ether: ethyl acetate = 10: 1) gave the pure title product, yielded 166.8 mg yield 97%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1777-82-8, its application will become more common.
