Abstract
The reaction of 5-hydroxyindoles with ammonia, alkylamines, or dialkylamines in the presence of sulfites leads to the corresponding 5-aminoindoles. Partial or complete elimination of the substituent is observed in the case of indoles that have an electron-acceptor substituent (COOC2H5, COCH3).
