نویسندگان
چکیده
In the title compound, C(11)H(8)Cl(2)N(2)O, the benzene and pyridazine rings are tilted by 8.6 (1)° relative to each other. In the crystal, pairs of inter-molecular N-H⋯O hydrogen bonds form centrosymmetric dimers. π-π contacts with centroid-centroid distances of 3.698 (2) and 3.751 (1) Å and halogen-halogen inter-actions [3.379 (1) Å] also stabilize the structure.

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).
