Versuchsvorschrift
5-Nitrotryptamine (6 mmol) is dissolved in pyridine (15 ml) and treated with acetic anhydride (7 mmol) 20 min at 27° C. The solvents are removed in vacuo, the residue taken into a small amount of methanol and passed through a short plug of silica with 5% methanol-chloroform eluent. Product-containing fractions are pooled, evaporated and dried thoroughly at <0.1 mm Hg.
