I didn't try this reaction yet. I watched video published here iodo-ketone amination. There I saw freebase is black and powder changed colour when preparing for crystalization. Maybe it was black cause of iodine being leaving group as opposed to bromine.
Questions to comfirm:
1. Results above are from ethyl acetate as a solvent ?
2. Have you done this reaction with EA and bromoketone, does freebase look any different?
3. I noticed from video that crystals from EA look glass like, while NMP are lot whiter. I read your post about stereochemistry of 4-MMC how S and R enantiomers form different looking crystals, are both of these crystals equally racemic?
4. Did you notice any difference in subjective effect between EA and say NMP in final product?
