실험 절차

10 g (0.06 mol) of 2,3-dichloromaleic acid was dissolved in 100 ml of water. Then, to the resulting solution 5.55g (0.05 mol) of 4-fluoroaniline was added dropwise over a period of 5 min. at reflux temperatures under agitation. Upon addition of 4 -fluoroaniline, a white crystal separated out immediately but the reaction was allowed to preceed for two hours. After cooling, the crystal was separated by filtration and fully rinsed with water to obtain 12.7g (yield, 97.7%) of N-(4-fluorophenyl)-2,3-dichloromaleimide (Sample No. 1) having an average grain size of 10μ. An analysis by gas chromatography showed that the N-(4-fluorophenyl)-2,3-dichloromaleimide had a purity of 96.2%.
