The synthesis method of 4- (p-toluenthio) thiopheno [2,3-c] pyridine-2-formamide has the following ways.
First, it can be initiated by nucleophilic substitution reaction. First, take a suitable thiophenopyridine derivative and make it react with p-toluenthiol in a suitable solvent in the presence of a suitable base. Bases such as potassium carbonate, sodium carbonate, etc., the solvent can be selected as N, N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO) and other aprotic polar solvents. This reaction condition requires precise temperature control, generally between 60 and 100 ° C. The reaction takes several hours to more than ten hours, depending on the activity of the reactants. After this step, an intermediate containing thioether structure can be obtained. Subsequently, the intermediate is formylated, and a suitable formylating agent, such as oxalyl chloride, phosphorus oxychloride and N, N-dimethylformamide (DMF), is used to react at low temperature to room temperature, and formyl groups can be introduced. Finally, by amidation reaction, ammonia or amine compounds are used in condensing agents such as 1 - (3 -dimethylaminopropyl) - 3 -ethyl carbodiimide hydrochloride (EDC · HCl), N, N ′ -dicyclohexyl carbodiimide (DCC), etc., in suitable solvents such as dichloromethane and chloroform to form the target product 4- (p-toluenthio) thiopheno [2,3 - c] pyridine-2 -formamide.
Second, the heterocyclic construction of thiophene and pyridine can also be started. The thiophenopyridine parent nucleus is constructed by a multi-step cyclization reaction using suitable sulfur-containing and nitrogen-containing feedstocks. For example, the cyclization and condensation reaction of thiophenopyridine derivatives with sulfur-containing enone compounds and pyridine derivatives is catalyzed by Lewis acids such as aluminum trichloride and zinc chloride to form a thiophenopyridine skeleton. Afterwards, the skeleton is modified by thiolylation, using reagents such as p-toluenesulfonyl chloride or p-toluenethiol, and a p-toluenesulfonyl group is introduced under base catalysis. Finally, the target product is obtained by formylation and amidation in a similar manner as described above.
Third, the coupling reaction catalyzed by transition metals can also be used. In the presence of transition metal catalysts such as palladium catalysts (such as tetra (triphenylphosphine) palladium (0), palladium acetate, etc.) and ligands (such as triphenylphosphine, bis (diphenylphosphine) ethane, etc.), in a suitable solvent (such as toluene, dioxane, etc.), the coupling reaction occurs under the action of a suitable solvent (such as toluene, dioxane, etc.) to obtain an intermediate containing thioether structure. Subsequent to the formylation and amidation steps, the 4 - (p-toluene thio) thiopheno [2,3 - c] pyridine-2 - formamide was successfully synthesized.

4- (p-toluenthio) thiopheno [2,3-c] pyridine-2-formamide is a kind of organic compound. Its physical and chemical properties are quite important, and it is related to the behavior of this compound in various situations.
First talk about its physical properties. The color state of this compound, or its solid state, is often powdery or crystalline, which is caused by intermolecular forces and arrangements. Determination of the melting point can help determine its purity and thermal stability. If heated to a specific temperature, the molecular vibration intensifies, the lattice structure disintegrates, and it melts into a liquid state. The value of this melting point can be used to distinguish the difference between this compound and others.
As for solubility, it may have a certain solubility in organic solvents, such as dichloromethane and chloroform. Due to the principle of "similar miscibility", there may be a suitable interaction between the molecules of the organic solvent and the molecules of the compound. However, in water, the solubility may be very small, because the polarity of the water molecule is strong, and the polarity of the compound is relatively weak, and the force between the two is difficult to match the hydrogen bond between the water molecules.
In terms of chemical properties, it contains amide groups and has a certain reactivity. The carbonyl group of the amide can react with the nucleophilic reagent. If attacked by the nucleophilic reagent, the electron cloud density of the carbonyl carbon changes, triggering a series of subsequent reactions. The thiophenopyridine ring and the p-toluene thio-group part also endow it with unique chemical activity. The π electron cloud distribution of the thiophenopyridine ring makes it prone to electrophilic substitution reactions, and the stability of the aromatic ring makes it able to participate in various chemical reactions, providing a variety of possibilities for organic synthesis. The sulfur atom of the p-toluene thio-group has a lone pair of electrons, which can be used as a nucleophilic check point or participate in coordination chemistry reactions to form complexes with metal ions, thereby changing the electronic structure and chemical activity of the compound.
