into the pyridine moiety by reductivedehalogenation with zinc, and choosing deuterated acetic acid as the acidic medium. Pyridine 2H-labelled nornicotine derivatives were then formed in two reaction steps, a condensation reaction with N-vinylpyrrolidinone followed by catalytic hydrogenation. The deuteromethylation of these monodeuterated nornicotines was achieved by reduction of the corresponding ethyl
