Abstract

PURPOSE: The catalytic reduction of 2-(2,6-dichloroanilino)phenylglycolic acid is effected in the presence of a catalyst under acidic conditions to produce with industrial safety title compound used as nonsteroidal anti-inflammatory analgesic.
CONSTITUTION: The compound of formula I is hydrogenated in a lower aliphatic acid, preferably acetic acid, containing a mineral acid, preferably sulfuric acid, in the presence of a noble metal catalyst, preferably palldium on carbon, under normal pressure to 80 atmospheric pressure, preferably 30-50 atmospheric pressure, to give the objective compound of formula II. The compound of formula I is obtained from the compound of formula III through similar reactions to the above and the compound of formula III is prepraed by the hydrolysis of the compound of formula IV with 1.2W3 moles of alkali, preferably caustic soda, in an organic solvent as ethanol under heating.
