Synthetic Route of 6575-00-4, These common heterocyclic compound, 6575-00-4, name is 3,5-Dichlorobenzonitrile, its 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.
step 1-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 R-3b.
The synthetic route of 6575-00-4 has been constantly updated, and we look forward to future research findings.
