Versuchsvorschrift

To a solution of (E)-2-(6-methoxyindan-1-ylidene)-ethylamine (736 mg, 3.89 mmol) and triethylamine (0.59 g, 5.84 mmol) in tetrahydrofuran (20 ml) was added acetyl chloride (0.37 g, 4.70 mmol) gradually dropwise on an ice bath and the mixture was stirred at room temperature for 2 hours. This reaction mixture was poured in water and extracted with ethyl acetate. The extract was washed serially with saturated saline and water and dried over anhydrous magnesium sulfate. Finally the solvent was distilled off under reduced pressure to provide (E)-N-[2-(6-methoxyindan-1-ylidene)ethyl]acetamide (yield 1.0 g, 90%).
