To prepare 2 - (4 -hydroxyphenyl) - 4 -methylthiazole-5 -ethyl carboxylate, the following ancient method can be used.
First, 4-hydroxyacetophenone is used as the starting material, and it is placed in a suitable reaction kettle with thioacetamide and ethyl bromoacetate. The kettle is first filled with an appropriate amount of inert gas to remove the oxygen in it and avoid oxidation disturbance. Then add an appropriate amount of alkali, such as potassium carbonate, to catalyze the reaction. Control the temperature within a certain range and slowly heat it in a water bath or an oil bath to about 80-100 ° C, so that the reaction lasts for several hours. In this step, the amount of alkali is accurate and the temperature is stable, so that the reactant can be fully mixed to promote its cyclization, and the precursor of 2- (4-hydroxyphenyl) -4-methylthiazole-5-ethyl carboxylate is produced.
After the reaction is completed, the product is treated in a conventional method. The reaction solution is first poured into an appropriate amount of water and extracted several times with an organic solvent such as ethyl acetate. The organic phase is collected and dried with anhydrous sodium sulfate to remove the water. Then the organic solvent is removed by vacuum distillation to obtain a crude product.
The crude product still contains impurities and needs to be refined. The method of recrystallization can be used to select a suitable solvent, such as a mixed solvent of ethanol and water. The crude product is dissolved in this mixed solvent, heated until dissolved, and then slowly cooled to allow the crystals to slowly precipitate. Suction filtration, with a small amount of cold solvent to rinse the crystals to remove surface impurities. Finally, the crystals are dried at a suitable temperature to obtain pure 2- (4-hydroxyphenyl) -4-methylthiazole-5-carboxylate ethyl ester.
This synthesis method, although the steps are complicated, is cautious step by step and strictly abides by the conditions to obtain pure products.

2-% 284 - hydroxyphenyl% 29 - 4 - methylthiazole - 5 - carboxylic acid ethyl ester, Chinese name or 2 - (4 - hydroxyphenyl) - 4 - methylthiazole - 5 - carboxylic acid ethyl ester. The physical properties of this substance are as follows:
Looking at its properties, it is mostly solid at room temperature. As for the color, it may be white to light yellow powder, which is caused by the synthesis process and the influence of impurities. Its particle size may vary due to the preparation process. Usually, the powder particle size is finer, and the number of mesh may reach hundreds. This helps to disperse uniformly in the reaction system and participate in the reaction.
The melting point is about a certain temperature range. This temperature is the result of the combined effect of intermolecular forces and lattice energy. When the external temperature rises near the melting point, the lattice structure begins to disintegrate, the thermal motion of the molecules intensifies, and the substance gradually melts from the solid state to the liquid state. The value of the boiling point needs to be determined under specific pressure conditions. The boiling point reflects the energy required for the material to transform from the liquid state to the gas state, and is also related to the intermolecular forces.
As for solubility, it has a certain solubility in organic solvents, such as common ethanol and acetone. The polarity of ethanol is similar to the partial structure of the compound. According to the similar principle of compatibility, it can form intermolecular forces with it to help it dissolve. In water, the solubility is relatively low, due to the poor matching between the polarity of water molecules and the overall polarity of the compound, and the hydrophobic groups in the compound have a greater influence.
In terms of density, its density may be slightly higher than that of water, which is determined by the molecular structure and the type and number of constituent atoms. The atoms in the molecule are closely arranged and the atomic weight is large, resulting in a relatively high mass per unit volume.
The physical properties of this compound are of great significance to its application in the fields of chemical industry, pharmaceutical synthesis, etc. Knowing its solubility, a suitable solvent can be selected to facilitate the reaction and product separation; melting point and boiling point data are indispensable for operations such as material purification and distillation, providing a basis for precise control of reaction conditions and optimization of processes.
