The method of preparing 3-bromo-6- (cyclopropyl) pyridine is quite complicated and requires delicate handling. One method is to take the pyridine as the base and interact with the suitable brominating agent under specific conditions to obtain bromine-containing pyridine derivatives. If liquid bromine is used as the brominating agent, in the presence of a catalyst or under light conditions, bromine atoms can selectively replace hydrogen atoms at specific positions on the pyridine ring to generate 3-bromopyridine.
Then, let 3-bromopyridine react with the cyclopropylation reagent. This cyclopropylation reagent can be selected from Grignard reagents such as cyclopropyl magnesium halide. In organic solvents such as anhydrous ether or tetrahydrofuran, 3-bromopyridine undergoes nucleophilic substitution with cyclopropyl magnesium halide, so that cyclopropyl is introduced into the 6-position of the pyridine ring, and then 3-bromo-6- (cyclopropyl) pyridine is obtained.
However, in this process, the reaction conditions need to be strictly controlled. If the temperature is too high, side reactions will easily occur, resulting in impure products; if the temperature is too low, the reaction rate will be slow and take a long time. And the purity and dosage ratio of the reagent used have a great impact on the reaction. The solvent used also needs to be dried and anhydrous to prevent the Grignard reagent from decomposing in contact with water and damaging the reaction.
There are other methods, which can first protect some active check points on the pyridine ring with suitable protective groups, and then carry out bromination and cyclopropylation reactions. In this way, the selectivity of the reaction can be improved and the occurrence of side reactions can be reduced. However, this operation step is more complicated, and each step of the reaction needs to be carefully planned, and the introduction and removal of protective groups need to select suitable conditions and reagents to achieve the purpose of preparing high-purity 3-bromo-6- (cyclopropyl) pyridine.
