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^
