Reaction Steps
(-)-N-α-phenylethylphthalamic acid was prepared from phthalic anhydride and (-)α-phenylethylamine by the method of Mann and Wastom (J. Chem. Soc., 1947, 510). The ester of this phthalamic acid with racemic α-ethynyl-3-phenoxybenzyl alcohol was prepared by the method of Human and Mills (J. Chem. Soc., 1949, S77). The individual (-)(+) and (-)(-) ester diastereoisomers were separated by chromatography (HPLC) and then hydrolysed with a slight excess of alkali to recover the resolved α-ethynyl-3'-phenoxybenzyl alcohol.
