Adding a certain compound to certain chemical reactions, such as: 6575-00-4, name is 3,5-Dichlorobenzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 6575-00-4, name: 3,5-Dichlorobenzonitrile
A 100 ml round bottom flask was charged under a stream of nitrogen with 3,5-dichlorobenzonitrile (R-3a,7.0 g, 40.69 mmol) and anhydrous DMF (75 mL). To the solution was added sodium methoxide (2.26 g, 44.76 mmol) and resulting solution was stirred further at RT for 24 h. When the reaction was complete, aqueous 10% HCl added dropwise to the reaction vessel. The crude mixture was extracted with EtOAc and sequentially washed with aqueous acid, water and brine. The EtOAc extracts were dried (Na2SO4), filtered and the solvent was removed in vacuo to afford a crude solid which was recrystallized from hexane/acetone to afford 5.9 g (86%) of 5-chloro-3-methoxy-benzonitrile.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3,5-Dichlorobenzonitrile, and friends who are interested can also refer to it.
