Simple methods for the labelling of N-methyl amines using isotopically labelled methyl iodide

Fellows, Ian,Carr, Richard M.,DeBoeck, Nigel,Montgomery, Stephen,Waterhouse, Ian,Sutherland, Derek R.

, p. 1127 - 1143 (2007/10/03)

Methods for the synthesis of isotopically labelled N-methyl amines using the target amine and isotopically labelled methyl iodide in a quaternisation/dequaternisation strategy are described. The method has been further refined to allow the synthesis of such amines without any isotopic dilution.
