Related Products of 450-91-9, A common heterocyclic compound, 450-91-9, name is 4-Fluoro-2-methoxyaniline, molecular formula is C7H8FNO, 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.
iii: Intermediate 3 (1.0 eq) and cesium carbonate (2.0 eq) and corresponding phenylamine (1.2 eq) were added into a dry reaction flask. Dry DMF was used as reaction solvent, N2 was used to remove water vapor and oxygen. Then catalyst and ligand Pd(AcO)2 (0.1 eq) and Xantphos (0.1 eq) were added. The reaction mixture was transferred to a 60 C oil bath, 6~7 hours. After the reaction completed, the mixture was filtered and evaporated. Intermediate 4 was gained. The yield was 50%.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
