Category: 95970-08-4

Some common heterocyclic compound, 95970-08-4, name is 2,5-Dibromoanisole, molecular formula is C7H6Br2O, 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. COA of Formula: C7H6Br2O

(0957) [00336] Into a lOG-mL round-bottom flask, purged and maintained under an inert atmosphere of nitrogen, was added l,4-dibromo-2-methoxybenzene (2.60 g, 9.78 mmol), benzyl piperazine- 1-carboxylate (2.37 g, 10.8 mmol), Pd2(dba)3-CHCij (0.508 g, 0.490 mmol), XantPhos (0,583 g, 0.980 mmol), and NaOtBu (2.82 g, 29.3 mmol) followed by toluene (40 mL). The reaction mixture was stirred, for 3 h at 80 C and then concentrated in vacuo. The resulting crude product was purified by FCC eluting with ethyl acetate/petroleum ether (1 : 10) to afford benzyl 4-(4- (0958) 131 (0959) 144628010 vl bromo-3-methoxyphenyl)piperazine-l-carboxylate as a brown solid (2 g, 50%). LCMS (ESi, m/z): 405, 407 [M?H]+

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 95970-08-4, its application will become more common.

Application of 95970-08-4, 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 95970-08-4 as follows.

The product of the third step, 2,5-dibromoanisole 1080 g and DMF 5500 mL, was added to the reaction vessel.Stirring, control temperature was added to 688 g of aluminum trichloride in batches at 80-100 C. The GC tracks until the reaction is over.After the reaction was completed, dichloroethane and water were added, and the mixture was separated.The oil phase was washed with water and separated, and the obtained oil phase was desolvated to obtain a black solid 2,5-dibromophenol 548 g, a content of 98%, and a yield of 53.3%.

According to the analysis of related databases, 95970-08-4, the application of this compound in the production field has become more and more popular.
