実験手順
To a mechanically stirred solution of meso-2,3-dibromosuccinic acid (27.6 g, 0.100 mol) in alcohol (200 ml) was slowly added benzylamine (85 g, 0.80 mol) at ambient temperature. After complete addition the mixture was refluxed overnight. A heavy precipitate of salts appeared. The mixture was cooled to 50° C. and concentrated hydrochloric acid was added until pH was 4-5. The precipitate was filtered off, washed several times with water and alcohol and dried.
