I was really looking into this method with the demethylation, but for right now i dont have time to fuck around with it. It seems like a very straight forward and simple synthesis that can be scaled up.

Read the sources that Rhodium points out about SIBX. Not only are they very informational but they're understandable and pretty interesting to say the least.
I dont think this method is getting or has gotten enough attention. Unfortunately, im unable at the time to test it out, even with most of the components collected. :(
Its not listed on that methylation page but maybe it should bee :)
