Patent ID: 7126003

Claim:
A process for producing a compound represented by formula (II): wherein R 1 represents a 3-fluoro-2-pyridyl group; R2 represents a hydrogen atom, a hydroxyl group, an alkoxyl group having 1 to 6 carbon atoms which may have substituent(s), an alkanoyl group having 1 to 6 carbon atoms which may have substituent(s), an alkenoyl group having 2 to 6 carbon atoms which may have substituent(s), an aryl group which may have substituent(s), an aryloyl group which may have substituent(s) or an aralkyl group which may have substituent(s); and R3 represents an alkyl group having 1 to 6 carbon atoms which may have substituent(s) or an alkenyl group having 2 to 6 carbon atoms which may have substituent(s); which comprises treating a compound represented by formula (I) with an enzyme capable of asymmetrically hydrolyzing an ester: wherein R 1 , R 2 and R 3 are each as defined above.
