Abstract

PURPOSE: To prepare the titled compound at a low reaction temperature, without side reactions, by reacting an indole derivative having oxazolidinone ring with a compound such as triethyloxytetrafluoroborate, etc., and hydrolyzing the reaction product.
CONSTITUTION: The compound of formula II (R is alkyl), e.g. 5-(4-indolyloxymethyl)-3-isopropyloxazolidin-2-one, etc. is used as a raw material, and is made to react with the compound of formula (R')3OBF4 (R' is alkyl) to obtain a quaternary ammonoium-type iminoether derivative of formula III, which is hydrolyzed to afford the objective compound of formulaI. The whole reaction steps can be carried out at a low temperature between room temp. and 50°C.
