Participants

Reaction Steps

N-acetylimidazole (0.61 g) was added to a solution of 4-amino-2,6-diethylpyridine (0.61 g) in toluene (10 ml) and the mixture was heated at reflux for 16 hours. The mixture was cooled to ambient temperature and solvent was removed by evaporation. The residue was purified by flash chromatography eluting with ethyl acetate to give 4-(N-acetylamino)-2,6-diethylpyridine (B) (0.66 g) as a solid, m.p. 74°-78° C.; NMR (CDCl3): 1.26(t, 6H), 2.18(s, 3H), 2.74(q, 4H), 7.18(s, 2H), 7.75(broad s, 1H); mass spectrum (chemical ionisation, ammonia): 193(M+H)+.
