I. Estevez et al., Pyridazines. XV. Synthesis of 6-aryl-5-amino-3(2H)-pyridazinones as potential platelet aggregation inhibitors, J HETERO CH, 35(6), 1998, pp. 1421-1428
Several 3(2H)-pyridazinones with amino groups at the 5-position of the pyri
dazine nucleus have been prepared. The 6-aryl-5-halo-3(2H)-pyridazinones ob
tained from mucochloric and mucobromic acid lead to the corresponding 5-alk
ylamino-3(2H)-pyridazinones, which were tested as platelet aggregation inhi
bitors.
