The chiral compound was prepared by several alternative procedures. Acid hydrolysis of the known racemic ester (I) gave carboxylic acid (II), which was converted into acid chloride (III) by using oxalyl chloride in benzene. This was either condensed with (S)-2-phenylglycinol (V) or with (S)-4-benzyloxazolidine-2-one (VI) to provide the diastereomeric mixtures of amides (VI) or imides (VII), respectively. After chromatographic separation of the required (S,S)-diastereoisomers, the title compound was obtained by acid hydrolysis of the (S,S)-amide or by hydrolysis of the corresponding imide with NaOH.
