Chiral discrimination of 1-phenylethylamine (<B>1</B>) by diastereomeric salt formation with bile acids is described. X-ray crystallographic studies of the salts between cholic acid (<B>2a</B>) and (<I>R</I>)-, (<I>S</I>)-, and (<I>RS</I>)-<B>1</B> reveal that more densely packed (<I>S</I>)-<B>1</B>+<B>2a</B> salt crystallizes preferentially by treatment of <B>2a</B> from racemic <B>1</B>.
