I figured that the first reaction just adds a bromine to the meta position but I don't know what step ii) does. The only thing I can think of is the base gets rid of the alpha hydrogen next to the carbonyl... thenThen perhaps the -venegative carbon now attacks iodine? But that seems a bit off to me.

What does addition of iodine and base do this case?
