Abstract

PURPOSE: To obtain the titled high-purity compound useful as a synthetic raw material for perfumes or amino acids, in high selectivity in one stage, by reacting inexpensive aniline with ethylene glycol, etc. in the vapor phase in the presence of a catalyst Pd/C, etc.
CONSTITUTION: One mole of an aniline is reacted with 0.05W5mol of ethylene glycol in the vapor phase in the presence of a catalyst containing a metal of Group VIII, e.g. Pd/C, Pd/CaCO3 or Pt-C, at a liquid space velocity based on the catalyst of 0.01W5l/l-catalyst/hr and 250W400°C under ordinary pressure to give indole or a derivative thereof, e.g. 5-methoxyindole. Alternatively, one mole of a nitrobenzene is reacted with 0.05W5mol ethylene glycol and 1W30mol hydrogen gas.
