Abstract

A method for the preparation of 3- (trisubstituted benzoyl) -propionic acid of the formula **(See formula)** wherein R1 is an alcohol group of 1 to 4 carbon atoms, an alkoxy group of 1 to 4 carbon atoms, or hydroxyl, and R3 and R3 are, the same or different from each other, an alcohol group of 1 to 4 carbon atoms, an alkoxy group of 1 to 4 carbon atoms, hydroxyl, halogen or an alcoholyl group of 1 to 4 carbon atoms, or are, in conjunction with each other, an alcoholylenedioxy group of 1 to 3 carbon atoms, provided that when R1 is the alkoxy group, at least one of R2 and R3 is the alkoxy group or the alcoholylthio group, or R2 and R3 are, in conjunction with each other, the alcoholylenedioxy; when R1 is the alcoholic or hydroxyl group, R2 and R3 are, the same or different, the alkoxy group, the alcoholylthio group or, in conjunction with each other, the alcoholylenedioxy; when R2 and R3 are methoxy, R1 is an alkoxy group with 2 to 4 carbon atoms or hydroxyl and when R2 is the alcohol and R3 is methoxy, R1 is an alkoxy group with 2 to 4 carbon atoms, which comprises reacting a compound of formula **(See formula)** wherein R1, R2, and R3 have the same meaning as set forth above, with a reactive derivative of succinic acid, and hydrolyze the resulting compound, if necessary.
