Abstract
A process for preparing 2- (6-methoxy-2-naphthyl) propionic acid, which consists of maintaining a non-aqueous solution of a compound of the formula: ** (see formula) ** Where r represents a cyano group or the radical -ch = noh in an aliphatic alcohol of up to 10 carbon atoms and a strong acid selected from the group consisting of organic acids, inorganic acids and lewis acids, at a temperature of at least 60º c, for a time comprised between 1 hour and 4 days until an orthoester of 2- (6-methoxy-2-naphthyl) propionic acid is formed, add water to the reaction mixture and maintain it at an elevated temperature, preferably at room temperature. Boiling temperature, until dl 2- (6-methoxy-2-naphthyl) propionic acid is formed; separate this compound from the reaction mixture and solve it to give the 2- (6-methoxy-2-naphthyl) propionic acid.
