# How to carry out cyclization of 1‐(2‐methylbutyl)‐2‐nitrocyclohexane?

How the cyclization can take place as there is no other functional group than $$\ce{NO2}?$$

One way that I can think of is photochemical bromination which occurs selectively at tertiary center which then can be promoted to give cation in polar medium. Nitro group on being reduced to amino group will attack on carbocation, thus closing the ring.

The problem here is that there are three tertiary centers and radical close to functional group will be more stable than the one at the far tertiary center on side chain.

How would you handle this conversion?
