Versuchsvorschrift

A solution of indan-2-yl-methylamine (5.55 g, 37.7 mmol) and triethylamine (5.67 g, 56.0 mmol) in 100 mL THF was stirred at 5° C. and propionic anhydride (5.15 g, 39.6 mmol) added dropwise. After the mixture was stirred for 18 h at room temperature, the solvent was removed and ethyl acetate/water were added. The organic layer was washed with water and dried over MgSO4. The filtrate was concentrated to give a brown oil (8.79 g, 97%).
