I was actually after methoxylation, not methylation, MeI cannot possibly do that, did you MEAN to use MeI/di-MeSO4.
I am actually working with tryptamines, rather than indole itself, as the tryptamines are more available (serotonin, melatonin, mexamine,), indole itself is a b$*%( to actually come by these days.
I wanted to prepare mexamine (5-MeO-T), starting from serotonin, and perhaps prepare melatonin from the formed mexamine, although I could always buy melatonin, and decarboxylate it with CaO/NaOH to yield mexamine.
