Electric Literature of 363-47-3,Some common heterocyclic compound, 363-47-3, name is 3,5-Difluoro-4-methoxyaniline, molecular formula is C7H7F2NO, 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.
General procedure: The relevant halogenated heterocycle (1.0equiv.), substituted aniline (2.0 equiv.) and TFA (5.0 equiv.) were takenup in TFE (0.1 M) and heated under microwave irradiation conditionsat 140 C for 30 min before being concentrated in vacuo. The residuewas resuspended in EtOAc:THF (1:1, 20 mL/mmol), washed with saturatedNaHCO3 solution (20 mL/mmol), and the aqueous phase wasfurther extracted with EtOAc:THF (1:1, 3 × 15 mL/mmol). The combinedorganic extracts were washed with brine, dried (MgSO4) andconcentrated in vacuo. The resultant residue was purified via columnchromatography and/or triturated as specified to afford the desired compound.
The synthetic route of 363-47-3 has been constantly updated, and we look forward to future research findings.
