Methyl 3-amino-5-(4-chlorophenyl)thiophene-2-carboxyate

Guanfu "Methyl 3 - amino - 5 - (4 - chlorophenyl) thiophene - 2 - carboxyate", this is the English name of an organic compound. According to organic chemistry nomenclature, "Methyl" refers to an alkyl group containing one carbon, often referred to as "-CH 🥰". "3 - amino" refers to the amino group attached to the third position of the thiophene ring, and the structure of the amino group is "-NH ²". " 5 - (4 - chlorophenyl) ", which means that the 5-position of the thiophene ring is connected with a 4-chlorophenyl group, and the 4-position of the 4-chlorophenyl-phenyl group (-C H) is replaced by a chlorine atom (-Cl), and its structure is -C H Cl." thiophene - 2 - carboxyate "indicates that this is a thiophene - 2 - carboxylic acid ester. The thiophene ring has a five-membered heterocyclic structure with a sulfur atom in the ring, and the carboxylic acid ester part is obtained by the reaction of the carboxyl group (-COOH) with the alcohol to form an ester. Here, because of" Methyl ", it is a methyl ester, that is, -COOCH.
In summary, the chemical structure of this compound should be: with a thiophene ring as the core, 3-position amino-NH 2, 5-position 4-chlorophenyl-C H Cl, and 2-position methyl ester-COOCH. Its structure can be schematically as follows: thiophene ring-NH 2 (3) -C H Cl (5) -COOCH (2). In this structure, each atom is connected by covalent bonds to form a specific spatial configuration, showing the unique chemical properties of the organic compound.

To prepare methyl 3-amino-5- (4-chlorophenyl) thiophene-2-carboxylic acid ester, the method is as follows:
First take an appropriate amount of 4-chlorothiophenol and place it in the reaction kettle. Replace the air in the kettle with nitrogen to keep it oxygen-free. Then slowly add potassium carbonate and stir well to make the two fully contact. Then drop into the solution containing halogenated methyl acetate and control the temperature within a certain range. This is because too high or too low temperature can affect the rate and yield of the reaction. During the reaction, continue to stir to make the reactants mix evenly to promote the reaction.
After the reaction is completed, the product is extracted with an appropriate organic solvent to separate the organic phase. After drying with anhydrous sodium sulfate to remove the moisture. Then the organic solvent is distilled under reduced pressure to remove the crude product.
Then the crude product is purified by column chromatography. Select the appropriate silica gel as the stationary phase, elute with a specific proportion of eluent, and collect the fraction containing the target product. After the solvent evaporates, a pure methyl 3-amino-5 - (4-chlorophenyl) thiophene-2-carboxylic acid ester can be obtained. The whole process requires fine operation, and attention to the control of conditions in each link to obtain satisfactory results.

The physical properties of methyl-3-amino-5- (4-chlorophenyl) thiophene-2-carboxylic acid esters are particularly important, which is related to the application and characteristics of this substance.
Looking at its appearance, at room temperature, it is mostly white to white crystalline powder. This form has an impact on the operation, storage and transportation of many chemical and pharmaceutical fields. Because it is a powder, its fluidity is crucial, which is related to the transportation and mixing uniformity of materials in the production process.
