    Abstract: A 2-ethoxypropionic acid derivative or pharmaceutically acceptable salt thereof is provided to be useful for preventing and treating diabetes more effectively by dually acting on a peroxisome proliferator-activated receptor alpha or gamma. A method of reaction formula (1) for preparing 2-ethoxypropionic acid derivatives includes the steps of: (i) coupling a compound of the formula 8 with a compound of the formula 9a in an organic solvent in the presence of a base to prepare a compound of the formula 10; (ii) reducing the compound of the formula 10 to prepare a compound of the formula 11; and (ii) subjecting the compound of the formula 11 and isocyanate(R3-NH-CH=O) or isothiocyanate(R3-NH-CH=S) to a coupling reaction and a hydrolysis reaction in the presence of a base, followed by thereto adding an acid to prepare a compound of the formula 1 through acidification.
