35203-44-2, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 35203-44-2 as follows.
General procedure: A mixture of 9-bromo-10-(bromomethyl)anthracene (2) (1 mmol) and the relevant N-alkyl imidazoles(4a-f) or N-benzyl benzimidazoles (7a-e) in THF (15 ml)was refluxed at open condition for 24 h. By this time the products8a-f and 9a-e appeared as yellow precipitates which were isolatedby filtration, washed with little THF, then with ether and were airdried.Yield: 85-89percent (imidazolium salts) and 80-87percent (benzimidazoliumsalts).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 35203-44-2, and friends who are interested can also refer to it.
