Abstract

PURPOSE:To obtain the subject compound useful as a raw material for a thianaphthene derivative having thromboxane synthesis inhibiting action in high yield by treating a 3-halogenated thiophene with a base and adding a Lewis acid to a reaction system in the reaction of the treated 3-halogenated thiophene with an alkylene oxide. CONSTITUTION:A compound of formula I (R<1> to R<3> are H, alkyl or aryl; X is halogen) (e.g. 3-bromothiophene) is treated with a base. Subsequently, the system is incorporated with a Lewis acid (preferably boron trifluoride-ethyl ether complex) and the compound is made to react with a compound of formula II (R is H, alkyl or aryl) (e.g. ethylene oxide) to obtain a 2-(3-thienyl)ethanol derivative of formula III [e.g. 2-(3-thienyl)ethanol]. The process is excellent from industrial point of view.
