Application of 131860-97-4, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.131860-97-4, name is (E)-Methyl 2-(2-((6-chloropyrimidin-4-yl)oxy)phenyl)-3-methoxyacrylate, molecular formula is C15H13ClN2O4, molecular weight is 320.73, as common compound, the synthetic route is as follows.
A slurry containing methyl (E)-I- {2-[6~chloropyrimidin-4-yloxy]phenyl} -3-methoxyacrylate (80.9g at 99%, 0.25mols), potassium carbonate (52.8g at 98%, 0.375mols) and 2- cyanophenol (33.6g at 97.5%, 0.275mols) in MIBK (16OmIs) was heated to approximately 6O0C. A solution of DABCO (0.28g, 0.0025mols) in MlBK (1 OmIs) was added. The mixture was heated to 8O0C and held at this temperature for 360 minutes. Water (30OmIs) was charged to the reaction, maintaining the temperature in the range 70-800C. The mixture was stirred for 70 minutes then settled and the lower aqueous phase separated. The MIBK solution (235.3g) contained methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4- yloxyjphenyl} -3-methoxyacrylate (41.0%w/w) 95.8% of theory.; c) Coupling of methyl rE)-2-{2-[6-chloropyrimidin-4-yloxylphenyl|-3-methoxyacrylate with 2-cvanophenol in MIBK with lmol% DABCO added after the 2-cyanophenol, that is, last. EPO
Statistics shows that 131860-97-4 is playing an increasingly important role. we look forward to future research findings about (E)-Methyl 2-(2-((6-chloropyrimidin-4-yl)oxy)phenyl)-3-methoxyacrylate.
