541-59-3, 1) Ethyl-2,5-dioxo-2,5-dihydro-1H-pyrrole-1-carboxylate 9.7 g (0.1 mol) of maleimide are solubilized in 50 ml of ethyl acetate and 1.1 ml of N-methylmorpholine at 5 C. 1.1 ml of ethyl chloroformate are added dropwise. The mixture is stirred for 1/2 hour. The insoluble material is removed by filtration. The filtrate is washed with 50 ml of water. The organic phase is dried over MgSO4 and is then concentrated under vacuum. The oil obtained is purified on Merck Geduran silica gel (40-63 mum). Elution: CH2Cl2/ACOEt 66/34. 16.9 g are isolated with a yield of 50%. Mass spectrum: M/z=170.1 (ES+) theoretical M=169
541-59-3 Maleimide 10935, apyrrolines compound, is more and more widely used in various fields.
