Iodomethane just makes my head hurt a bit. I learned about it in my chem book as neucleophilic substitution. But when you're talking about adding a methyl group to a compound with it, it kind of flips your thinking. Not only that, but this reaction would theoretically produce hydroiodic acid, if I'm not mistaken, which may mess up tryptamine. Are there any other compounds capable of methylating tryptamine in perhaps an easier fashion or without such reactives invloved?
