The bis(β.-diketone) compounds, 3,3'-(pyridine-2,6-diyl)bis(1- phenylpropane-1,3-dione) monohydrated (1a-H2O) and 3,3'-(pyridine-2,6-diyl)bis(1-(pyridin-2-yl)propane-1,3-dione) monohydrated (1b-H2O) were prepared by Claisen condensation of the appropriate ketone and dimethyl pyridine-2,6-dicarboxylate ester. Compounds 2,6-bis(5- phenyl-17Y-pyrazol-3-yl)pyridine dihydrated (2a-2H2O) and 2,6-bis(5-(pyridin-2-yl)-17Y-pyrazol-3-yl)pyridine monohydrated (2b-H 2O) were synthesized by reaction of the appropriate bis(β.-diketone) compounds and hydrazine monohydrate. © 2010 Bentham Science Publishers Ltd.
