Looking at these amines and ethylchloride, it seems that none of them really readily react with water (amines will dissolve in it).
As Rhodium said "use ammonia in an alcohol", this seems the answere, and from what it seems the alcohol would not have to be anhydrous. I'm not saying that the reaction could be done with ammonia vodka (maybe it could ?), as thats just too crude, but say recitified spirit could be used, as the alcohol(h20) is mearly being used as a solvent for the ethyl chloride and the ammonia.
I know a man who will try this in the new year, probably with Ammonia IPA. I wait to hear his results
