    Abstract: PROBLEM TO BE SOLVED: To provide a process of simply producing an optically active aryloxycarboxylic acid derivative useful as an intermediate of drugs from an inexpensive raw material. SOLUTION: The optically active aryloxycarboxylic acid derivative can be obtained by the acid hydrolysis of an optically active aryloxycarboxylic acid ester derivative represented by formula (3). The optically active aryloxycarboxylic acid ester derivative represented by formula (3) can be obtained by reacting an α-bromocarboxylic acid ester derivative represented by formula (1) with an aryloxy derivative represented by formula (2).
