Abstract :

Five nuclear substitution derivatives of 4- acetyl pyridine (2a to 6a) were prepared via N-oxidation followed by either nitration or arylation in the yield of 60-80%. Substitution at 2- position is promoted due to the electron withdrawing and meta- directing ability of acetyl group at 4- position making the pyridine N-oxide vulnerable to attack at C-2.
