実験手順

100 mg of succinic acid monochloride are dissolved in 2 ml of anhydrous acetonitrile. 1.5 equivalents of aniline (102 mg) are added at room temperature and the reaction mixture is kept stirred for 30 minutes. 100 ml of 0.005M sulfuric acid are then added and the solution is extracted with ethyl ether (3×3 ml). The ether phases are combined and washed with water to neutrality and then dried over anhydrous MgSO4. The ether is then filtered and evaporated under reduced pressure to give 90 mg of N-phenylsuccinamic acid.
