## 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

Abstract
Lithiation of diethyl methylphosphonate (1) with n‐butyllithium followed by carbonation with [^14^C]carbon dioxide and esterification with diazoethane afforded high specific activity triethyl [1‐^14^C]phosphonoacetate (4) in 62% yield.
