So I was thinking that to de-brominate the chemical 'bromocriptine' I could simply go with a gingard reaction, but then some issues arised, and now I am a bit confused.

Apparently using ether with Mg, and H20 with BC (bromocriptine) would not produce the BrMg-ergocristine reagant to react with water. Not only this, but the reaction itself is fairy difficult to judge its completion.
        What is an easier way to do this, without losing too much of my chemical due to its sensitivity? Once it is into the ergocristine its simple as baking a cake, but from what I've looked into removing the bromo is the hardest part.
