Versuchsvorschrift

To a solution of 3-(2-amino-ethyl)-1H-indol-5-ol hydrochloride (10.0 g) in 450 mL of absolute ethanol was added 1.6 g of paraformaldehyde and 5.4 mL of glacial acetic acid. The mixture was heated to reflux for 1.5 h then allowed to cool to rt. The white precipitate so formed was collected by filtration and dried under vacuum to yield 5.9 g of 2,3,4,9-tetrahydro-1H-β-carbolin-6-ol hydrochloride.
