✦ Synopsis


The drug 5-phenyl-5-phenyl -d -hydantoin was prepared employing a f i v e step synthesis starting%m readily available benzene-&.

Two key intermediates, benzoin-d , and benzil-&, were prepared, containing only one f u l l y l a b e d d phenyl-d group. The precursor benzll-d was condensed w i t h urea t o generde the labelled drug, dipheny4ydantoin-3. This new probe possesses only one f u l l y labelled phenyl group making i t suitable f o r metabolic studies and as an internal standard f o r c d i n e d GC-MS-conputer analyses o f body f l u i d extracts. Synthetic procedures as well as complete spectral data o f precursors and the labelled drug are presented.
