実験手順

5.56g of the thusly resulted 4-fluoroanilinium 2,3-dichloromaleate was suspended in 40 ml of water and allowed to react for 2 hours at reflux temperatures. Upon cooling the reaction mixture, precipitated crystal was separated by filtration to obtain 4.8g of N-(4-fluorophenyl)-2,3-dichloromaleimide melting at 240°-242° C (not corrected) at a yield of 95.0%. An analysis by gas chromatography showed the product had a purity of 99.2%.
