Versuchsvorschrift

A mixture of 4-[2-cyano-5-(3-pyridylmethoxy)-phenoxy]-4-(2-methylphenyl)butanoic acid, thought to be the (R)-enantiomer, (50 mg), dicyclohexylamine (0.5 mL) and diethyl ether (10 mL) is stirred at ambient temperature for 18 hours. The resulting precipitate is collected and washed with diethyl ether, to give dicyclohexylammonium 4-[2-cyano-5-(3-pyridylmethoxy)phenoxy]-4-(2-methylphenyl)butanoate, thought to be the (R)-enantiomer, (30 mg) in the form of a white solid, m.p. 92-93° C.
