The synthesis method of 3-amino-2-bromo-4- (trifluoromethyl) pyridine is not detailed in the classic "Tiangong Kaiwu", but there are many chemical methods to follow at present.
One method is to start with a compound containing a pyridine structure. Before the appropriate position of the pyridine ring, bromine atoms are introduced by halogenation. To obtain accurate substitution, it is necessary to control the reaction conditions, such as temperature, ratio of reagents and reaction time. Pyridine derivatives and brominating reagents can be reacted slowly in a suitable solvent or supplemented with a catalyst, so that bromine atoms fall into the expected 2-position.
Next, trifluoromethyl is introduced. This step is usually carried out with a reagent containing trifluoromethyl by a specific reaction mechanism. Either nucleophilic substitution or free radical reaction, trifluoromethyl is connected to the 4-position of the pyridine ring. For nucleophilic substitutes, appropriate active substrates and nucleophilic reagents need to be selected to ensure a smooth and efficient reaction; for free radical reactions, the amount of initiator and the reaction environment need to be regulated to make the generation and reaction of free radicals orderly.
As for the introduction of amino groups, it can be done after both bromine and trifluoromethyl are in place. Or by aminolysis, ammonia or ammonia derivatives interact with the previous product. Adjust the reaction conditions such as pH and temperature, so that part of the ammonia replaces suitable atoms or groups, and finally obtain 3-amino-2-bromo-4 - (trifluoromethyl) pyridine. After the reaction is completed, it needs to be separated and purified, such as column chromatography, recrystallization, etc., to obtain a pure product.
