چکیده
In the title compound, C21H24N2O2Si, a new pyridazin-3(2H)-one derivative, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether are located on the same side of the pyridazinone ring and the C-C-O-Si torsion angle is -140.69 (17)°. In the crystal, mol-ecules are linked by pairs of strong N-H⋯O hydrogen bonds into centrosymmetric dimers with graph-set notation R 2 (2)(8). Weak C-H⋯π inter-actions are also observed.

A set of regioisomeric 2-substituted pyridazin-3(2H)-ones containing a 3-oxo-3-phenylprop-1-en-1-yl fragment at either position 4, 5 or 6 and 2-substituted pyridazin-3(2H)-ones containing the same fragment both at positions 4 and 5 have been synthesized and evaluated as antiplatelet agents. The study allows the identification of a new highly potent platelet aggregation inhibitor (4c).
