Abstract

C^14^‐labelled O,N‐dimethylhydroxyurethane is synthesized from C^14^‐labelled dimethylsulfate and N‐hydroxy‐urethane. It is further converted without purification into O,N‐^14^‐C‐dimethyl‐hydroxylammoniumchloride, which was then nitrosated with sodiumnitrite in acidic medium to give N‐Nitroso‐O,N‐^14^C‐dimethylhydroxylamine in 49% yield.

## Abstract A convenient procedure to synthesize 2–^14^C‐dinitroso‐hexahydropyrimidine (DNHP) is described. The synthesis begines with the condensation of ^14^C‐formaldehyde and propylenediamine‐1,3 in benzene with azeotropic removal of water. The resulting bases are isolated from the reaction mixt

14C labelled Metribuzine was synthetised in a five step synthesis firom sodium [l-14C]pivalate (trimethyl acetic acid) via o-brom0-[2-~~C]pinacoline (l-bromo-3,3-dimethyl-butan-2-on) and trimethyl [2-14C]pyruvic acid. The total yield was 30% (calculated on sodium pivalate).
