Process for the preparation of E-2-propyl-2-pentenoic acid and physiologically compatible salts thereof

A novel process for the preparation of E-2-propyl-2-pentenoic acid, as well as the physiologically compatible salts thereof is described, in which 2-bromo-2-propyl-pentenoic acid ethyl ester is used as the starting compound. The bromine is split off with a cyclic tertiary amine in acetonitrile as the solvent and preferably the E-isomer of the ethyl ester is formed. The free acid is obtained by subsequent saponification under careful conditions and optionally, preferably using the corresponding carbon dioxide salts in aqueous acetone solution, is converted into the salt form.
