A revisited synthesis of 2-aryl-6-methyl-1,2-dihydro-1H-pyridin-4-ones and their saturated analogues 2-aryl-6-methylpiperidin-4-ols is described. A five steps procedure, using the sulfinimine chemistry, to prepare a key intermediate β-(6-chloronicotinic)-β-amino ester is also reported. In vivo spontaneous working memory activity of these compounds has been investigated in the mouse. Results obtained with 2-(3-chlorophenyl)-6-methyl-1,2-dihydro-1H-pyridin-4-one 9b, the most effective derivative in this model, have been reported.

2-(3-chlorophenyl)-6-methyl-1,2-dihydro-1H-pyridin-4-one 9b shows the most effective spontaneous working memory activity in mice, suggesting potential as anti-amnesiant agents.
