Not sure about that last step.  An amido group is a moderate activator.  The para position would work, but those two at the meta position...I don't see them working.

This would give you a 1,3,5-tribromo- .

OK -

Im running outta ideas! How is this??

This is aside the point.  Other than those minor things, your syntheses are very creative and do work.  I would prefer them over mine.   

Thanks, Im glad we can discuss those minor things, that way i can learn .

Looks good.  First step you forgot H₂SO₄.  In the acetylation step, I would use an acyl chloride, but that's just me.

In the diazotization step, use HBr instead of H₂SO₄, this will allow you to eliminate the need for an additional reagent because your Br^- from your diazo salt will come from HBr and will allow for the later Sandmeyer reaction.

You got it.
