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. 3401-47-6, name is 1-Bromo-2-methoxynaphthalene, A new synthetic method of this compound is introduced below., Product Details of 3401-47-6
(A) 2-Acetyl-5-bromo-6-methoxy-naphthalene (Compound V) A suspension of 43 g of anhydrous AlCl3 and 24.6 g (0.313 mole) of acetyl chloride in 200 ml of 1,2-dichloroethane at 10 C. was cooled to 0 C. and added dropwise under stirring with a solution of 59.25 g (0.250 mole) of 1-bromo-2-methoxy-naphthalene in 150 ml of 1,2-dichloroethane. The resulting solution was stirred for 15 minutes then poured into a cold solution of 300 ml of water and 100 ml of 2 N hydrochloric acid. The organic phase was separated, washed first with 100 ml of 1 N hydrochloric acid and then with 100 ml of water, dried under vacuum and the obtained residue was crystallized from 2-butanol. Yield 68.11 g (98%).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
