実験手順

A mixture of 28 g of p-phenoxyaniline and 28 g of dichloromaleic anhydride in 200 ml of glacial acetic acid was heated at reflux for 3 hours. Upon subsequent cooling, N-phenoxyphenyl-2,3 -dichloromaleimide crystallized and was collected by filtration. The 46 g (92% of theory) of crude material was washed with petroleum ether and air-dried. An analytical sample was prepared by recrystallization from glacial acetic acid, producing golden flakes of N-(p-phenoxyphenyl)-2,3-dichloromaleimide melting at 180°-181° C.
