The method of preparing ethyl-2- (4-hydroxyphenyl) -4-methyl-5-thiazole carboxylic acid ester has been recorded in ancient books. One method is as follows:
First take an appropriate amount of 4-hydroxybenzaldehyde, place it in a clean reactor, and add the corresponding organic solvent to fully dissolve it. Then slowly add a specific proportion of ethyl acetoacetate, and add a little basic catalyst such as potassium carbonate. Control the temperature in a moderate range, about 50 to 60 degrees Celsius, and stir the reaction number. At this time, the two condensation reactions occur, forming key intermediate products.
After the reaction is completed, the reaction solution is cooled, and the pH is adjusted to be weakly acidic with an appropriate acid solution, so that the intermediate product is precipitated. Filter and collect, and wash it several times with an organic solvent to obtain a pure intermediate product.
Take the obtained intermediate product and place it in another reactor with thioformamide, add an appropriate amount of solvent, such as ethanol, etc. Raise the temperature to 80 to 90 degrees Celsius to fully react. In this step, the intermediate product is cyclized with thioformamide to obtain ethyl-2 - (4-hydroxyphenyl) -4-methyl-5-thiazole carboxylic acid ester. After the reaction is completed, the solvent is removed by cooling and vacuum distillation, and then the product is purified by recrystallization with a suitable solvent, such as ethanol-water mixed solvent, and finally a high-purity target product can be obtained. This preparation method has clear steps and controllable conditions. It is actually a good strategy for synthesizing ethyl-2 - (4-hydroxyphenyl) -4-methyl-5-thiazole carboxylic acid esters.

Ethyl-2- (4 - Hydroxyphenyl) -4 - Methyl - 5 - Thiazolecarboxylate is an organic compound. During storage and transportation, many key matters need to be paid attention to.
When storing, the temperature and humidity of the first environment should be the first. A cool and dry place should be found to avoid high temperature and humidity. Due to high temperature, or the molecular activity of the compound is enhanced, it will cause decomposition or deterioration; if the humidity is too high, it may absorb moisture and affect the purity and stability. This is like an ancient treasure, a dry and cool place must be selected to prevent the object from spoiling.
Furthermore, it must be prevented from contacting with air. The compound may react with oxygen, carbon dioxide and other components in the air, so it should be stored sealed. Just like the ancients sealed treasures and used a secret device to prevent external intrusion.
When transporting, the packaging must be stable. Select appropriate packaging materials to ensure that the compound is not damaged or leaked during bumps and vibrations. And the transportation tools must also be kept clean to avoid mixing with other chemicals and avoid chemical reactions. Just like the ancients when transporting valuables, they must be loaded in sturdy containers and escorted by special personnel to prevent bumping and mixing.
