실험 절차
18.5g (0.1 mol) of 2,3-dichloromaleic acid was dissolved in 120 ml of water. To the resulting solution 8.9g (0.08mol) of 4-fluoroaniline was added dropwise over a period of 5 min. at reflux temperatures under agitation. The mixture was then allowed to react for 2 hours at reflux temperatures. Upon cooling the reaction mixture, precipitated crystal was separated by filtration to obtain 20.3g of N-(4-fluorophenyl)-2,3-dichloromaleimide melting at 239°-240° C (not corrected) at a yield of 98.1%. An analysis by gas chromatography showed the product had a purity of 95.5%.
