To prepare 3-thiophenoformamide, 2-amino-5-methyl, the method is as follows.
First, a suitable starting material, such as a compound containing a thiophene structure and a modifiable group at a specific position. By chemical means, methyl groups are introduced before the corresponding check point of the thiophene ring. This can be selected from an appropriate methylating agent, such as iodomethane, under suitable reaction conditions, such as base catalysis and in a suitable solvent, so that the two undergo a nucleophilic substitution reaction to form a 5-methyl-modified thiophene compound.
Then, an amino group is introduced into the compound. It can be done by multiple methods, such as nucleophilic substitution, reductive amination and other reactions with amino-containing reagents. If nucleophilic substitution is used, a halogenated thiophene derivative with suitable activity needs to be selected, and it can be reacted with ammonia or amine reagents at appropriate temperature, pressure and in the presence of a catalyst to successfully connect the amino group to the 2-position.
As for the construction of the amide part, the carboxyl-containing thiophene derivative can be reacted with ammonia or amine. The carboxyl group is first activated, such as converted to an acid chloride, treated with a reagent such as dichlorosulfoxide, and then reacted with ammonia or amine under mild conditions to obtain the 3-thiophene formamide structure.
During the entire synthesis process, it is necessary to carefully observe the conditions of each step of the reaction, such as temperature, solvent, catalyst dosage, etc., and make good use of separation and purification techniques, such as column chromatography, recrystallization, etc., to remove impurities and obtain pure target products 3-thiophenylformamide, 2-amino-5-methyl.
