3-(Dimethylamino)-1-(pyridine-2-yl)prop-2-en-1-one

3-(Dimethylamino)-1-(pyridine-2-yl)prop-2-en-1-one was synthesised based on the literature. The reaction of (2g, 16.5mmol) of 2-acetylpyridine and DMF dimethyl acetal(7.84g) were suspended in 11ml of xylene and stir this reaction mixture for 16h at 110℃. Into the resulting mixture 10 ml of hexane added yellow colour precipitate was formed and allows stirring for 20min at 3℃. Resulting mixture was filtered and dried in vacuum to get a yellow colour powder.

3-(Dimethylamino)-1-(2-pyridyl)-2-propen-1-one may be used in the preparation of the 5-(heteroaryl)isoxazole derivatives, 5-(2-pyridyl)isoxazole and 3-methyl-5-(2-pyridyl)isoxazole. It may also be used to synthesize 7-(2-pyridyl)-1,2,4-triazolo[1,5-a]pyrimidine.

3-(Dimethylamino)-1-(2-pyridyl)-2-propen-1-one (1-(2′-Pyridyl)-3-dimethylamino-2-propen-1-one), an enaminone, is a hemilabile hybrid ligand. The preparation of cationic mononuclear rhodium(I) or iridium(I) complexes containing 3-(dimethylamino)-1-(2-pyridyl)-2-propen-1-one have been reported.
