英文摘要 | A practical synthesis of 6-4(-aminonaphthyl)-4,5-dihydro-3(2H)-pyridazinone (5) is described. The method involved the use of α-naphthylamine as the starting material followed by acetylation, acylation, hydrolysis, and cyclization with hydrazine hydrate to give target compound 5. Direct treatment of 2 with hydrazine hydrate resulted in the isolation of cyclized product 4 in addition to the hydrolyzed compound 5. |
