چکیده
In the title mol-ecule, C(19)H(15)F(3)N(2)O, the benzene rings of the tolyl and trifluoro-methyl-phenyl groups form dihedral angles of 64.1 (2) and 38.5 (2)°, respectively, with the pyridazine ring. The CF(3) group is disordered over two orientations, with site-occupancy factors of ca 0.56 and 0.44.

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).

The title compound, C(18)H(16)N(2)O, is a new dihydro-pyridazin-3(2H)-one derivative synthesized in one step by condensation of α-benzyl-idene-γ-tolyl-butenolide with hydrazine. The mol-ecule is not planar; the tolyl and pyridazine rings are twisted with respect to each other making a dihedral angle of 27.35 (9)° and the benzyl ring is nearly perpendicular to the pyridazine ring with a dihedral...

In the title compound, C(15)H(12)F(3)N(3), the pyrazolo[1,5-a]pyrimidine system ring is essentially planar with a maximum deviation from the mean plane of 0.014 (1) Å. The 4-tolyl group makes a dihedral angle of 14.1 (1)° with the pyrazolo[1,5-a]pyrimidine ring system. The crystal packing is stabilized mainly by van der Waals forces.
