Versuchsvorschrift
A mixture of one molar equivalent of N-(4-carboxyphenyl)maleimide is reacted with excess thionyl chloride at 50° C. for three hours. The excess thionyl chloride is distilled off, and the residual product recrystallized from benzene to obtain pure N-(4-(chlorocarbonyl)phenyl)maleimide.
