Are you trying to make pyrrole or porphyrin heterocycle from nitro compound?

Then

1) First, you need to reduce it to amine. Raney nickel or iron-in-acid reduction would do fine.

2) Paal-Knorr synthesis with dicarbonyl compound ( https://www.organic-chemistry.org/namedreactions/paal-knorr-pyrrole-synthesis.shtm ).

3) After that Rothemund reaction to porphyrin

Thank you so much Mikhail Nekrasov will proceed

That's a tough transformation! In general C-NO2 activation is challenging, but can be done. See: Article The Suzuki–Miyaura Coupling of Nitroarenes

Article The Buchwald‐Hartwig Amination of Nitroarenes

Maybe you can convert it to a diazonium, then to a cyanide, then hydrolyze? That's a lot of steps with potentially harsh conditions thought.
