541-59-3,541-59-3, Maleimide is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Methylchloroformate (4.4 niL, 56.7 mmol, 1 eq) was added to a solution of maleimide (5.5 g, 56.7 mmol, 1 eq) and NMM (6.2 mL, 56.7 mmol, 1 eq) in 200 niL of EtOAc at 0 0C. The suspension was stirred at 0 C for 30 minutes, filtered and washed with EtOAc. Filtrate and washings were combined and washed with cold water and dried over anhydrous Na2SO4. After filtration and evaporation under vacuum a pink solid was obtained. Purification by column chromatography on silica gel (Hexane-EtOAc, 1:1, v/v) provided the product (4.8 g, 55%).
As the paragraph descriping shows that 541-59-3 is playing an increasingly important role.
