This report describes an improvedsynthesis of enantiomericallypure (S)-2-[4-(Dimethylamino)phenyl]-2,3-dihydro-N-[2-hydroxy-3-[4-[2-(1-methylethoxy)-phenyl]-1-piperazinyl]propyl]-1,3-dioxo-1H-isoindole-5-carboxamide (RWJ69442), a potent and selective αla-adrenergic receptor antagonist for the treatment of benignprostatichyperplasia. The synthesis highlights less hazardous reagents, easier purification
