The two compounds were labelled by ^14^C on the hydroxyimino methyl group substituted on the 2 positions of the pyridinium ring. The convenient pyridinium lithiated intermediates were formylated with N‐methyl ^14^C‐formanilide. The hydroxyimino methyl groups were synthezised by reaction of the ^14^
The ^14^C labelling of three compounds : HI‐6, TMB‐4 and pyrimidoxime is described from ^14^C‐formic acid, sodium salt. The compounds were prepared by lithiation and formylation with N‐methyl (^14^C)‐formanilide followed by introduction of the hydroxylamine moieties and alkylation of the pyridine. R
