Abstract
As an aid to the study of the metabolism and disposition of LY217896 in laboratory animals and humans, ^14^C‐labeled material was prepared utilizing formic‐[^14^C] acid as the starting material. Uniformly labeled LY217896‐[^13^C] was also synthesized for use in metabolite identification. Formic acid, cyanogen bromide, and potassium cyanide which were >99% isotopically enriched with ^13^C were utilized; once the appropriate starting materials were synthesized, the synthesis of the ^13^C and ^14^C‐labeled materials were parallel.

The partial ergoline LY228729 (1) which was a potent 5HT 1A agonist has been studied clinically. Somewhat later, a related analog, (S)-di-n-propyl-(8-isoxazol-5-yl-1,2,3,4-tetrahydronaphthalen-2-yl)amine (2a) which in addition to potent 5HT 1A agonist activity was a muscarinic antagonist, was chosen
