| Abstract: | Analogues of 6 4 substituted phenyl]pyridazinones have potent activity against platelet aggregation. The synthesis of analogues of 6 4 (4 substituted piperazine)phenyl] 4,5 dihydro 3(2H)pyridazinones is carried out. Many reactions such as Friedel_Crafts reaction,hydrolysis, cyclation, bromination and N_alkylation were used to sythesze the title compounds. PTC method was used to N_alkylation,yields were raised greatly. Their stracture were identified with element analysis and 1HNMR. |
