Reference of 13275-42-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 13275-42-8 name is 2-(2-Bromophenyl)-1H-benzo[d]imidazole, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
General procedure: 2-(2-Bromophenyl)benzimidazole (1 mmol), substituted aldehyde (1.2 mmol), NaN3 (1.8 mmol), Cu (10mol%), L-proline (20 mol%), and Cs2CO3 (1 mmol) were added to DMF in a 50 mL round bottom flask, and then the mixture was refluxed at 80 C for 16 h under nitrogen atmosphere. TLC was monitored the reaction till completed, and then the reaction mixture was cooled to room temperature. The mixture was poured into the dichloromethane, washed with brine and water. The organic layer was concentrated with evaporator, and the residue was purified by column chromatography on silica gel to give the target compound (A-4 to A-37).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-(2-Bromophenyl)-1H-benzo[d]imidazole, and friends who are interested can also refer to it.
