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. 5467-58-3, name is 1-Bromo-4-methoxynaphthalene belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. category: ethers-buliding-blocks
3-a. Synthesis of 1-methoxy-4-{4-(naphthalen-1-yl)phenyl}naphthalene 1-Methoxy-4-{4-(naphthalen-1-yl)phenyl} was synthesized as follows. 1-Bromo-4-methoxynaphthalene (25 g, 0.105 mol), 4-(naphthalen-1-yl)phenylboronic acid (30.4 g, 0.137 mol), potassium carbonate (21.9 g, 0.16 mol), tetrakis(triphenylphosphine)palladium(0) (2.4 g, 0.01 mol), water (25 mL), tetrahydrofuran (75 mL) and toluene (75 mL) were stirred in a 250 mL round-bottom flask for 12 hours under reflux. After completion of the reaction, the reaction mixture was cooled to room temperature and extracted with ethyl acetate (300 mL) and water (1000 mL). The organic layer was dried with magnesium sulfate and concentrated under reduced pressure to obtain a solid. The solid was dissolved in hot toluene (400 mL) and then filtered. The filtrate was recrystallized in methanol (800 mL). The resultant solid was filtered and washed with hexane (300 mL) to obtain a product (20 g, 0.055 mol, 52.6%).
The synthetic route of 5467-58-3 has been constantly updated, and we look forward to future research findings.
