Unexpected Hydrazinolysis Behaviour of 1-Chloro-4-methyl-5H-pyridazino[4,5-b]indole and a Convenient Synthesis of New [1,2,4]-Triazolo[4’,3’:1,6]pyridazino[4,5-b]indoles

Unexpected Hydrazinolysis Behaviour of 1-Chloro-4-methyl-5H-pyridazino[4,5-b]indole and a Convenient Synthesis of New [1,2,4]-Triazolo[4’,3’:1,6]pyridazino[4,5-b]indoles

Reaction of the title compound with hydrazine in the presence of air gives the 1-unsubstituted parent system via oxidative dehydrazination of the 1-hydrazino intermediate. The latter can be obtained in high yield by carrying out the hydrazinolysis step under inert gas, and it is smoothly converted i...
