## Abstract Carbon‐13 and carbon‐14 labeled forms of the title compound have been prepared from the correspondingly labeled forms of 8‐chloro‐1‐methyl‐6‐phenyl‐4H‐__s__‐triazolo[4,3‐a][1,4]benzodiazepine (__3__)Alprazolam is the generic USAN name for this compound. . A modified and more convenient
The possibility that I ,4-dihydro-I-methyl-4-oxonicotinonitrile ( V ) is an intermediate in the biosynthesis of the alkaloid ricinine from nicotinic or quinolinic acid in Ricinus communis L. led to our interest in preparing the carbon-14 labeled compound. The 4oxonicotinonitrile ( V ) and the corres
