To prepare 2 - (4 - bromophenyl) thiazole-4 - carboxylate ethyl ester, the following method can be used:
Take 4 - bromoacetophenone as the starting material, add an appropriate amount of thioacetamide in an appropriate reaction vessel, use an alcohol solvent such as ethanol as the medium, add an appropriate amount of base, such as potassium carbonate, etc., and heat and reflux. In this step, the carbonyl group of 4 - bromoacetophenone undergoes nucleophilic addition-elimination reaction with thioacetamide, and undergoes intramolecular cyclization to obtain 2 - (4 - bromophenyl) thiazole-4 - carboxylic acid. < Br >
After the reaction is completed, cool the reaction liquid, adjust the pH value to acidic with dilute acid such as hydrochloric acid, have solid precipitation, filter, wash, dry, and obtain pure 2- (4-bromophenyl) thiazole-4-carboxylic acid.
Then, place the carboxylic acid in another reaction vessel, add anhydrous ethanol, and use concentrated sulfuric acid as a catalyst to heat for esterification. Concentrated sulfuric acid not only acts as a catalyst, but also absorbs the water generated by the reaction, causing the equilibrium to move in the direction of ester formation. After the reaction has been carried out for a period of time, stop heating and cool the reaction system.
The reaction solution is poured into ice water, extracted with an organic solvent such as ether, the organic phase is collected, dried with anhydrous sodium sulfate, filtered, and the solvent is evaporated to obtain a crude product. After purification by column chromatography or recrystallization, pure 2- (4-bromophenyl) thiazole-4-carboxylate ethyl ester can be obtained. The whole process needs to pay attention to the control of the reaction conditions. Temperature, pH and the proportion of reactants all have important effects on the reaction results.

2 - (4-bromophenyl) thiazole-4-carboxylic acid ethyl ester, this substance is an organic compound with specific physical properties. Its properties are often solid, mostly due to strong intermolecular forces. Under normal temperature and pressure, the molecules are arranged in an orderly manner and appear solid.
View its color, or white to light yellow. Because the molecular structure contains a conjugated system, it absorbs light of a specific wavelength, resulting in color appearance. The degree of conjugation and the nature of the substituent affect the color depth, and structural factors such as 4-bromophenyl cause its color range to be like this.
In terms of melting point, the melting point of the compound may be within a certain range. The melting point of organic compounds is closely related to the intermolecular forces. The molecules of this compound contain polar groups and aromatic rings, and there are van der Waals forces and dipole-dipole interactions between molecules, resulting in relatively high melting points.
In terms of solubility, it may have certain solubility in organic solvents such as dichloromethane, chloroform, N, N-dimethylformamide (DMF). Because these organic solvents and compound molecules can form Van der Waals forces, hydrogen bonds and other interactions, which help them disperse and dissolve. However, the solubility in water is poor, because its molecular polarity is relatively weak, its ability to form hydrogen bonds with water is limited, and the hydrophobic benzene ring and thiazole ring structure make it difficult to dissolve in water. < Br >
has low volatility. Due to the strong intermolecular force, high energy is required to overcome the force to vaporize it, and it evaporates slowly at room temperature and pressure.
The density is higher than that of water. Because the molecules contain atoms with large relative atomic mass such as bromine, the unit volume mass is increased, and the density is greater than that of water.
