Thanks to Armageddon for his input.
Just after I have posted it I found out the EDDA recipe uses dry ether. I don't think I can make it or get it.
If someone could come up with a variation that does not uses dry ether, I believe it would be a nice way to make the nitrostyrene. Hopefully better yield, better product and less work.
Unless I know for sure, I think I will instead use the more conventional way of making the nitrostyrene.
