실험 절차

Melatonin (126 mg) is dissolved in tetrahydrofuran (10 ml) in a 50 ml round-bottomed flask, sodium hydride (200 mg) is then added and the mixture is maintained at reflux (10 min). After cooling (0° C.), acetyl chloride is added and the mixture is kept stirring overnight (room temperature). After filtration and dilution (EtOAc), the organic phase is washed with water and then separated on a silica plate. N-[2-(1-Acetyl-5-methoxyindol-3-yl)ethyl]acetamide (1) is mainly obtained, along with a side product, N-[2-(1-acetyl-5-methoxyindol-3-yl)ethyl]diacetamide (10) (cf. Example 10).
