Abstract

PURPOSE: To obtain the title compound which is a raw material for preparing 5- bromoindoles selectively in a high yield, by electrolyzing a specific indoline in the presence of bromine or its compound to utilize the total amount of bromine for the bromination reaction effectively.
CONSTITUTION: An indoline, e.g. an 1-acylindoline, such as 1-formylindoline, 1- acetylindoline, etc. is electrolyzed in the presence of bromine or its compound, e.g. lithium, magnesium bromides, or tetramethyl ammoniym bromide in an organic solvent, e.g. acetonitrile, propionitrile, etc. at a temperature of 0W100°C, preferably 10W40°C with a necessary quantity of electricity to give the title compound. Preferably, platinum or carbon electrodes are used as the electrode, and the current density is in the range of 1W10 mA/cm2.
