Question HELP!!Orange color when 2b4m is dissolved in solvent

[whitelabel]

Hi

I am getting a light to medium orange colour mix once I dissolve the 2bromo4methylpropiophenone in either DCM or nmp. This is affecting the amination stage. When I start adding the ma40 the entire solution turns green on nmp and in DCM it gives a dark green layer floating on top.
I do not have sodium thiosulphate. Is there Nothing else I can do to proceed. I am having a tough time with later separation because of this.
One time I remove some orange part and added extra DCM, added the methylamine aqueous. The green layer did form but upon heating and leaving it for a while I was able to get a slightly yellow milky colour solution.
Any help would be appreciated.
I am using herrbars method and using nmp plus DCM as solvent.
Wondering if heating the solution to boil off some DCM will help and that might take away some or most of the excess bromine .

Appreciate any help on this

No, recrystalize your 2b4m from alcohol and normaly afther adding the methylamine it turn dark orange, and im shure yield wise the byproduct that causes the color did not hurt the yield at all.

The issue arises when adding ma40% there is a green colour layer that forms, I suspect these are related. How can I take care of the green layer when adding the ma40

Planning to wash the DCM solution with vitamin c and dw to get rid of excess bromine before amination.

Sodium thiosulfate wash will take care of any halogens leftover, what is your problem with the green color it dont hurt anything and you cant wash it just simply.
