Application of 707-07-3, 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 707-07-3 as follows.
4-Methylbenzenesulfonic acid (3.1 g, 16 mmol) was converted to N1-benzyl-4-bromobenzene-1,2-diamine (45 g, 160 mmol).And 500 mL of dichloromethane and o-trimethyl benzoate30 mL is added to the mixed solution and reacted for about 40 hours at room temperature under nitrogen. After the reaction was completed, the organic layer was concentrated under reduced pressure, washed with 40% methanol / water and sodium hydrogencarbonate / water, and dried to obtain a product. (22.3 g, yield 40%)
According to the analysis of related databases, 707-07-3, the application of this compound in the production field has become more and more popular.
