ethyl 1-{4-[(aminothio)peroxy]phenyl}-8-nitro-4,5-dihydro-1H-benzo[g]indazole-3-carboxylate → Ethyl 1-[3-(aminosulfonyl)phenyl]-8-nitro-4,5-dihydro-1H-benzo[g]indazole-3-carboxylate

Participants

Reaction Steps

This compound was prepared using the same procedures for Ethyl 1-{4-[(aminothio)peroxy]phenyl}-8-nitro-4,5-dihydro-1H-benzo[g]indazole-3-carboxylate of Example 2, where 3-(aminosulfonamido)-phenylhydrazine was used in place of 4-(aminosulfonamido)-phenylhydrazine. Its structure was confirmed by 1H NMR and MS (443, M+1). C20H18N4O6S, Calc.: C: 54.29; H: 4.10; N: 12.66; Found, C: 54.27; H: 4.09; N: 12.55.
