摘要: To produce N-tertiary butoxycarbonyl-maleinimide, maleinimide is reacted in the presence of a heterocyclic nitrogen compound having at least one tertiary nitrogen atom (as a base) with a more or less equimolar quantity of di-tertiary butyl-dicarbonate in a suitable solvent at temperatures of up to about 80.degree. C.
