Yes, that looks quite similar to the reaction I posted in your other thread. If you're doing this on a large scale then just distill the product. Any
remaining nitrile will come over first with your desired ketone at around 100-130C.
Or just do a normal work-up, dry, evaporate and dissolve the residue in some pet. ether and flash it through a small silica plug with minimal amount
of EtOAc. This wont remove the nitrile if there's any left but if you're continuing with the ketamin synthesis it wont really matter. The nitrile will
not brominate and the formed a-bromoketone (well the one that I made with 3'-methylphenyl) will crystallize upon the addition of a little methanol.
