Abstract
A process for preparing 2- (6-methoxy-2-naphthyl) propionic acid consisting of: A) heating a solution of an alkyl, aralkyl or alkenyl 2- (6-methoxy-2-naphthyl) propionate either in racemic form or as isomer d and a soluble metal bromide or iodide or a quaternary ammonium bromide or iodide in a inert solvent at a temperature of at least 100ºC until halogenolysis occurs, the alkyl, aralkyl and alkenyl groups having up to 12 carbons; B) acidifying the reaction mixture and removing 2- (6-methoxy-2-naphthyl) propionic acid, and C) resolving the racemic mixture to obtain d 2- (6-methoxy-2-naphthyl) propionic acid.
