Abstract

1. A process for preparing d 2- (6-methoxy-2-naphthyl) propionic acid, characterized in that it comprises the following steps: 1) (oxidize 2- (6-methoxy-2-naphthyl) propanal or 1 2- (6-methoxy-2-naphthyl) -l-propanol with: A) a solution of chromic acid, or B) at least one member selected from the group consisting of potassium permanganate, sodium permanganate, zinc permanganate, potassium manganate, and sodium manganate in an inert organic solvent, water, or mixtures thereof, or C) nickel peroxide in the presence of an inorganic base in an aqueous ether solvent, until d 2- (6-methoxy-2-mafethyl) propionic acid or a salt thereof is formed; 2) acidify, if necessary, the resulting reaction mixture to release 2- (6-methoxy-2-naphthyl) propionic acid; y 3) separate said 2- (6-methoxy-2-naphthyl) propionic acid from the reaction mixture.
