>>11030105React benzaldehyde (essential oil of bitter almonds) with nitroethane in the presence of a primary amine catalyst. This will undergo a nitroaldol condensation aka Henry reaction to yeild the beta nitropropene. That is then reduced with tin chloride to yeild phenyl-2-propanone which can be added to a messy and extremely toxic mix of aluminum, mercuric chloride, and nitromethane making methylamine in situ, creating the imine from the ketone and reducing again to the final product in one step. Extract with a non polar solvent and gas with hcl to get your final product. Now if any part of that didn't make sense then you shouldn't try it.
