## 4-Cyanopyridine -2,6-d 2 (5a-2,6-d 2 ), 3-cyanopyridine-2,6-d 2 (5b-2,6-d 2 ), and 2-cyanopyridine-4,6-d 2 (5c-4,6-d 2 ) were synthesized from the corresponding 2-, 3-or 4-pyridinecarboxylic acid N-oxides. These dideuterated products were characterized by their mass and NMR spectra.

2‐Trideuteriopyridine‐4,6‐d~2~ (1‐4,6‐d~2~), 3‐methylpyridine‐2,6‐d~2~ (2‐2,6‐d~2~), 3‐methylpyridine‐2,4,6‐d~3~ (2‐2,4,6‐d~3~), and 4‐trideuteriopyridine‐2,6‐d~2~ (3‐2,6‐d~2~) were synthesized from the appropriate 2‐, 3‐, or 4‐methylpyridine N‐oxides. These deuterated products were characterized by their ^1^H NMR and ^13^C NMR spectra. J. Heterocyclic Chem., 46, 213 (2009).

Dipole moments of 2-N-methylamino-5-nitro-6-methylpyridine (I) and 2-N-methylamino-3-nitro-6-methylpyridine (II) were determined in solvents of different polarity and basicity. The solvent effect is discussed in terms of the twoparameter (\*-) Kamlet-Taft expression. The solvent dependences of the
