Pyridazines. XV. Synthesis of 6-aryl-5-amino-3(2H)-pyridazinones as potential platelet aggregation inhibitors
Estevez, Isabel,Ravina, Enrique,Sotelo, Eddy
, p. 1421 - 1428 (2007/10/03)
Several 3(2H)-pyridazinones with amino groups at the 5-position of the pyridazine nucleus have been prepared. The 6-aryl-5-halo-3(2H)-pyridazinones obtained from mucochloric and mucobromic acid lead to the corresponding 5- alkylamino-3(2H)-pyridazinones,
