Abstract

PURPOSE: To obtain a benzoxazole derivative useful as pesticides, medicines, and a raw material for the synthesis of various chemicals, in high yield, by reacting a specific trithiocyclopropenium salt with an o-aminophenol.
CONSTITUTION: A trithiocyclopropenium salt of formula I: (R1 is lower alkyl group; X- is anion), e.g. triethylcyclopropenium perchlorate, is reacted with an o- aminophenol of formula II: (Y is H or aprotic substituent) in a solvent, e.g. methylene chloride, at 0W100°C to give a benzoxazole derivative of formula III. A base, e.g. potassium tent-butoxide, may be added to the reaction system in an amount of 1W2mol per mole of the compound of formula I.
