実験手順

500 g of 2,5-dihydro-3,4-dimethoxy-5-phenyliminopyrrol-2-one were stirred with 500 ml of concentrated hydrochloric acid in 2 l of water for 2 days at room temperature. Thereafter, the mixture was cooled and filtered under suction. 325 g of dimethoxymaleimide of melting point 126°-127° C. were obtained.
