To prepare 1H-pyrrole-2-carboxylic acid, 5-nitro-, ethyl ester, you can follow the following method.
Take the appropriate starting material first. If pyrrole is used as the group, it can be nitrified first. In a suitable reaction vessel, add pyrrole and an appropriate amount of nitrifying agent, such as a mixed acid of concentrated nitric acid and concentrated sulfuric acid. Control the reaction temperature, generally low temperature is appropriate to prevent excessive nitrification and side reactions. When the nitro is successfully introduced into the fifth position of pyrrole, 5-nitropyrrole is obtained.
Subsequently, carboxylation of 5-nitropyrrole is carried out. For example, carbon dioxide can be introduced into an alkaline solution system containing 5-nitro pyrrole, and the 5-nitro pyrrole can be reacted at a suitable temperature and pressure to connect the carboxyl group to obtain 5-nitro-1H-pyrrole-2-carboxylic acid.
The last step is esterification. Mix 5-nitro-1H-pyrrole-2-carboxylic acid with ethanol, and add an appropriate amount of catalyst, such as concentrated sulfuric acid or p-toluenesulfonic acid. Under the condition of heating and refluxing, the carboxylic acid and ethanol undergo esterification to form 1H-pyrrole-2-carboxylic acid, 5-nitro-ethyl ester. After the reaction, the pure target product can be obtained by separation and purification methods, such as extraction, distillation, recrystallization, etc.

1H-pyrrole-2-carboxylic acid, 5-nitro-, ethyl ester, this is a chemical substance. During storage, many matters need to be paid attention to.
First, the temperature and humidity of the environment are extremely critical. This substance should be stored in a cool and dry place. If the temperature is too high, it may cause its chemical properties to change and accelerate decomposition; if the humidity is too high, it may cause moisture decomposition, which affects the quality. Therefore, the warehouse temperature should be controlled within a suitable range, such as between 15 ° C and 25 ° C, and the humidity should be maintained at 40% to 60%.
Second, light should not be ignored. The substance may be sensitive to light, long-term light exposure, or trigger photochemical reactions, causing it to deteriorate. Therefore, when storing, it should be placed in a container protected from light, or stored in a place where light is difficult to reach.
Third, fire and explosion protection is essential. Because of its certain chemical activity, it is dangerous to encounter open flames, hot topics or combustion and explosion. Therefore, fireworks are strictly prohibited in the storage area. Electrical equipment must be explosion-proof and should be equipped with fire-fighting equipment.
Fourth, isolation from other substances cannot be ignored. This chemical may react with certain substances, such as oxidizing agents, reducing agents, etc. Therefore, it should be separated from such substances when storing to prevent accidents caused by interaction.
Fifth, the logo must be clear. The name of the chemical, specifications, hazardous characteristics and other information should be stated on the container, which is convenient for identification and management. In case of emergency, it is also helpful to respond quickly.
Sixth, regular inspection is indispensable. Regularly check whether the packaging is in good condition, whether there is leakage, deterioration and other phenomena. Once problems are found, they should be dealt with in time to prevent the harm from expanding. In this way, the safety and quality of 1H-pyrrole-2-carboxylic acid, 5-nitro-ethyl ester can be ensured during storage.
