14 N‐ and 15 N‐NMR spectra have been recorded for 2‐(aminomethyl)pyridine ( 1 ), tris[(2‐pyridyl)methyl]amine ( 2 ), and some of their protonated forms. For 1 , the most basic site is the aliphatic N‐atom, whereas for 2 the pyridine N‐atoms are more basic, in contrast to what might be expected for a tertiary aliphatic amine.
