Versuchsvorschrift

6-Bromo-N,N-dimethyl-1H-indole-3-methanamine (7.76 g, 30.6 mmol) and NaCN (1.95 g, 39.8 mmol, 1.30 eq.) were combined with DMF (40 mL) and water (40 mL). The mixture was heated to reflux for 6 hours, then cooled to rt. Aqueous 1N HCl (40 mL) was added, and the product was extracted with EtOAc. The organic layer was washed with water and dried (MgSO4). The solvent was removed in vacuo to give 5.70 g (79%) of the title compound, that was 79% pure by HPLC area, containing 14% 6-bromoindole. The material was used without purification in the subsequent step.
