ABSTRACT:
A process for the preparation of indole and derivatives thereof wherein an aniline is reacted with an ethanolamine in the vapor phase, the liquid phase or a mixed vapor-liquid phase. Various solid acids, metals and activated carbon can be used as catalysts for this reaction. The present invention makes it possible to prepare indole and derivatives thereof in a single step by using inexpensive compounds as the starting materials.
