In 30 ml. of 10% aqueous solution of dimethylamine, 3.4 g. (0.01 mole) of 2-[4-(6-chloro-2-quinoxalyloxy)phenoxy]propionic acid was added. After a dissolution, excess of dimethylamine and water were removed by evaporating them by a rotary evaporator and the residue was dried in vacuum to obtain 3.5 g. (yield: 91%) of a pale yellow object product having a melting point of 63° to 67° C.
