Abstract

A process for the preparation of 2- (6-methoxy-2-naphthyl) -propionic acid consisting of treating a compound of the formula: **(See formula)** where X is chlorine or bromine and each of the radicals R and R1 is hydrogen or methyl, with a catalyst selected from the group consisting of palladium on carbon, platinum and platinum oxide in the presence of hydrogen or with Raney nickel in an organic solvent inert until 2- (6-methoxy-2-naphthyl) -propionic acid is formed.
