A method to resolve the stereoisomers of an optically active compound
comprising an amine moiety. The method provides a mixture comprising two
stereoisomers of a compound comprising a amine moiety. The method
supplies l-fenchyloxyacetic acid, treats the mixture of stereoisomers
with that l-fenchyloxyacetic acid, and collects one of those two
stereoisomers having greater than a 99 percent enantiomeric excess.
