실험 절차

A 250 mL three necked round bottom flask equipped with a mechanical stirrer, thermometer, reflux condenser and addition funnel is charged with 2-[(2R)-2-(4-nitrophenyl)propyl]isoindoline-1,3-dione (25.02 g, 80.6 mmol) and toluene (200.0 mL). To this solution at room temperature was added anhydrous hydrazine (7.08 mL, 226.0 mmol). Reaction exothermed slightly and was stirred for 45 minutes, heated at 90° C.-95° C. until the disappearance of starting material. A massive precipitate formed by the end of the reaction. Cooled to room temperature and chilled to 0° C. before filtration. Concentration of the filtrate afforded (2R)-2-(4-nitrophenyl)propylamine (14.11 g, 97%) as an oil;
