Abstract
Mixtures of d 2-(6-methoxy-2-naphthyl)propionic acid and 1 2-(6-methoxy-2-naphthyl)propionic acid or soluble salts thereof are resolved with N-R-D-glucamine or salts thereof, where R is alkyl having 2 to 36 carbon atoms or cycloalkyl having 3 to 8 carbon atoms, to yield a product substantially enriched in d 2-(6-methoxy-2-naphthyl)-propionic acid.
