No attachement.
Are you sure your product is correct? It would be named 3-bromo-2-methylbutan-2-ol.
But making that from your starting point using the chemicals you've stated would be tricky (unless people know some chemistry I don't: which is likely).
You could eliminate the Br to 2-methylbut-2-ene, and then addition to that with Br2 producing the 3-bromo-2-methylbutan-2-ium carbocation. Which in theory could react with OH- forming your product. That would at least follow Markovnikov.
