As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 131860-97-4, name is (E)-Methyl 2-(2-((6-chloropyrimidin-4-yl)oxy)phenyl)-3-methoxyacrylate, molecular formula is C15H13ClN2O4, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Computed Properties of C15H13ClN2O4
A slurry containing methyl (?)-2-{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 isopropyl acetate (13OmIs) was heated to approximately 6O0C. A solution of DABCO (0.28g, 0.0025mols) in isopropyl acetate (1 OmIs) was added. The mixture was heated to 8O0C and held at this temperature for 360 minutes. The isopropyl acetate was removed by vacuum distillation to a maximum temperature of 8O0C. Toluene (160ml) was added to the distillation residues, maintaining the temperature between 60-700C, followed by water (265mls) which had been heated to 6O0C, again maintaining the temperature between 60-700C. The mixture was stirred for 40 minutes at 8O0C and then settled and the lower aqueous phase separated. The toluene solution (229.8g) EPO
With the rapid development of chemical substances, we look forward to future research findings about 131860-97-4.
