541-59-3, Maleimide is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Maleimide (12.0 g, 123.7 mmol) was dissolved in ethyl acetate (150 mL) in a 250 mL round-bottom flask, and the solution was cooled to approximately 0 C. A solution of N-methyl morpholine, (14.1 mL, 12.8 g, 126.2 mmol) in ethyl acetate (10 mL) was added dropwise over 15 min. A solution of methyl chloroformate (9.60 mL, 11.5 g, 123.7 mmol) in ethyl acetate (50 mL) was added dropwise, and the solution was warmed to room temperature and stirring for 2 h. The solution was diluted with ethyl acetate (100 mL) and washed with saturated aqueous sodium bicarbonate solution, water, and saturated sodium chloride solution. The organic layer was separated, dried over Na2SO4, and filtered. The supernatant was concentrated under reduced pressure to yield the title compound as a solid (15.9 g, 102.5 mmol, 82.9% yield). 1H NMR (500 MHz, CDCl3): delta 6.84 (s, 2H), 3.97 (s, 3H).

The synthetic route of 541-59-3 has been constantly updated, and we look forward to future research findings.
