541-59-3,541-59-3, Maleimide is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of maleimide (6.35 g, 65.4 mmol) in ethyl acetate (120 niL) at 0 C was added NMM (8.6 niL, 78.5 mmol), followed by methyl chloroformate (6.0 mL, 78.5 mmol). The reaction was stirred at 0 C for 30 min and r.t. 1 h. The solid was filtered off and filtrate was concentrated. The residue was dissolved in methylene chloride and filtered through a silica gel plug and eluted with methylene chloride to remove the red color. After concentration, the solid was triturated with ethyl acetate and petroleum ether to give a white solid (9.0 g, 88% yield).
541-59-3 Maleimide 10935, apyrrolines compound, is more and more widely used in various fields.
