Procedure

555 g of dimethoxymaleimide in 2 l of 5% strength NaOH were stirred for 2 days at room temperature. Thereafter, the mixture was acidified and extracted thoroughly with methylene chloride. After the organic phase had been separated off and the solvent removed in a rotary evaporator, 486 g of a product of melting point 41°-43° C. remained.
