摘要：
An optically active 1-phenylethylamine is reacted to a phosphine oxide carboxylic acid of a racemic modification shown by the following general formula (2): and a produced diastereomeric salt is separated using the difference in solubility against a solvent, which is subsequently decomposed by acid, so as to free and separate an optically active phosphine oxide carboxylic acid.
