  The present invention relates to a process for producing an optically active 3-(4-hydroxyphenyl)propionic acid useful as intermediates for medicines, through short steps in good yield and with high optical purity. More specifically, the present invention relates to a process for producing an optically active 3-(4-hydroxyphenyl)propionic acid of the formula (6): wherein R2 is an alkyl group; R5 to R8 are each independently a hydrogen atom or a substituent; and the symbol * is an chiral carbon atom, or a salt thereof, which comprises reacting a benzaldehyde of the formula (1): wherein R1 is a protective group; and R5 to R8 are each the same as defined above, with a glycolic acid derivative of the formula (2): wherein R3 is a hydrocarbon group; and R2 is the same as defined above, hydrolyzing the resulting product to give a cinnamic acid of the formula (4): wherein R1, R2 and R5 to R8 are each the same as defined above, or a salt thereof, and subjecting the resulting cinnamic acid (4) or a salt thereof to asymmetric hydrogenation to give an optically active phenylpropionic acid of the formula (5): wherein all the symbols are each the same as defined above, or a salt thereof, followed by deprotection.
