1 - (isopropyl) -1H -pyrrole-2,5 -dione, if you want to make it, there are various methods.
One method can be obtained by the condensation reaction of maleic anhydride and isopropylamine. First take an appropriate amount of maleic anhydride, place it in a clean reactor, dissolve it in an organic solvent such as dichloromethane or toluene, stir well to form a clear solution. Then slowly add isopropylamine dropwise. When adding dropwise, pay attention to the reaction temperature, preferably at a low temperature, between about 0-5 ° C, to prevent side reactions from occurring. After adding dropwise, gradually heat up to room temperature, and continue to stir the reaction for several times until the reaction is complete. After the reaction is completed, the reaction solution is poured into an appropriate amount of water, solids are precipitated, filtered by suction, and the filter cake is washed with water several times. After drying, the crude product of 1- (isopropyl) -1H-pyrrole-2,5-diketone can be obtained. After recrystallization, it is refined with a suitable solvent such as ethanol-water mixed solvent to obtain a pure product.
Another method uses pyrrole-2,5-diketone as the starting material and reacts with the isopropylation reagent. For example, isopropyl halide, such as isopropyl bromide or isopropyl chloride, is selected and reacted in an organic solvent in the presence of a base. Potassium carbonate or sodium carbonate can be selected for alkali, and N, N-dimethylformamide (DMF) or dimethyl sulfoxide (DMSO) can be selected for organic solvent. First add pyrrole-2,5-diketone, alkali and organic solvent to the reaction vessel, stir and mix, heat up to a certain temperature, such as 60-80 ℃, and then slowly add isopropyl halide, and the reaction time. At the end of the reaction, the reaction liquid was cooled, poured into water, extracted with an organic solvent, the organic phases were combined, dried with anhydrous sodium sulfate, and the solvent was removed by rotary evaporation. The obtained crude product was also purified by recrystallization to obtain the target product 1- (isopropyl) -1H -pyrrole-2,5 -dione.

1 - (isopropyl) -1H -pyrrole-2,5 -dione is an important compound in organic chemistry. In chemical reactions, it has quite a lot of characteristics.
This compound contains pyrrole ring and diketone structure, so it has special reactivity. Its pyrrole ring is aromatic and can participate in a variety of electrophilic substitution reactions, such as halogenation, nitrification, sulfonation, etc. Electrophilic reagents easily attack the α position of pyrrole ring, because the electron cloud density of this position is relatively high.
