In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 157335-97-2, name is 5-Bromo-4,6-dimethylpyrimidine, the common compound, a new synthetic route is introduced below. Recommanded Product: 157335-97-2
Step 3. Synthesis of 4-[4-(4,6-dimethylpyrimidin-5-yl)-3-fluorophenoxy]-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[3,2-c]pyridine (C14) A mixture of C13 (427 mg, 0.881 mmol), 5-bromo-4,6-dimethylpyrimidine (150 mg, 0.802 mmol), tris(dibenzylideneacetone)dipalladium(0) (147 mg, 0.160 mmol), tricyclohexylphosphine (90 mg, 0.32 mmol) and potassium phosphate (341 mg, 1.61 mmol) in 1,4-dioxane (4 mL) containing 5 drops of water was heated at 120 C. for 2 hours under microwave irradiation. The mixture was filtered, the filtrate was concentrated under reduced pressure, and the residue was purified by preparative thin layer chromatography on silica gel (Eluent: ethyl acetate) to give the product, which was used without further purification. Yield: 180 mg, 0.387 mmol, 48%. LCMS m/z 465.3 [M+H+].
The synthetic route of 157335-97-2 has been constantly updated, and we look forward to future research findings.
