Conditions were found for almost quantitative carboxylation of n-hexyllithium with l4CO2 to afford lithium [1-l4C] heptanoate. It was then possible to perform the reaction sequence lithium [1-l4C] heptanoate --+ [l-14C] heptan-1-01 + 1-bromo [l-14q heptane in one flask without isolation of intermed

## Abstract Existing methods have been adapted for the small scale synthesis of the title compounds in high yield. Modification of the iodoform reaction enables 1,3‐^14^C‐acetone (I) to be converted in over 95% yield to ^14^C‐iodoform (II) which is reduced by sodium aresenite to ^14^C‐methylene dii

## Abstract Diazepam‐^14^C and demethyldiazepam‐^14^C are synthesized from glycine‐1‐^14^C. Addition of diketene to diazepam‐^14^C leads to ketazolam‐^14^C. The reaction conditions for the formation of ketazolam from diazepam is studied using high‐pressure liquid chromatography in conjunction with
