Procedure: Succinic anhydride (2.27 g, 22.7 mmol) was added in portions to a hot solution of tryptamine (3.30 g, 20.6 mmol) and potassium acetate (2.23 g, 22.7 mmol) in acetic acid (10 ml). The reaction solution was heated at the boiling point for 3 h and subsequently stirred at RT overnight and the precipitate which had precipitated out was filtered off and washed with acetic acid and EtOH. Yield: 3.00 g (Ind-61, 60%) The reaction solution was heated at the boiling point for 3 h the precipitate which had precipitated out was filtered off washed with acetic acid and EtOH
