Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 74137-36-3, name is 1,3-Dibromo-5-methoxybenzene, A new synthetic method of this compound is introduced below., Recommanded Product: 1,3-Dibromo-5-methoxybenzene
A mixture of 3,5-dibromoanisole (10 mmol, 2.7 g)Diphenylamine (60 mmol, 10 g) was added to a 100 mL three-necked flask,A cuprous iodide (6 mmol, 1.2 g) was added under nitrogen,Potassium carbonate (60 mmol, 8.3 g),Phenanthroline (6 mmol, 1.2 g),50 mL of DMF,The reaction was carried out at 155 ° C for 3 days;The resulting reaction product is subjected to extraction,The extracted organic phase was evaporated to dryness with ethanol,Then recrystallized from ethyl acetate and petroleum ether,To give 4.02 g of intermediate C-1,
The synthetic route of 74137-36-3 has been constantly updated, and we look forward to future research findings.
