5-MeO-DIPT Synthesis from melatonin
5-MeO-DIPT: https://erowid.org/library/books_online/tihkal/tihkal37.shtm...
Here's what I thought about :
1. The amide is turned into a primary amine by NaOH, which is then neutralized.
2. The amine is alkylised by 2eq of 2-chloropropane.
What would be the condition of these reactions?
Step 1 requires heating in reflux for several hours. The only example I could find stated 16h at 100-110C, which seems like a lot of time. I also
don't know how hot the solution can be without destroying the melatonin.
2-chloropropane boils at 36C, so the solution would have to be cooler than that for step 2.

You didn't bother thinking about doing any literature research at all, did you?

The reaction isn't exactly the same and could be optimized for this particular synthesis. I did as much research as I could with the given means.

The synthetic route is straight-forward and has been elucidated, in detail, elsewhere.
Barring a discussion of interesting novel Chemistry, many of us will not provide assistance in the preparation of a drug that is schedule 1 or
forbidden just about everywhere (US since 2003, officially in 2004).
Aside, I would personally be disgusted if I had to sign an invasive waiver in order to buy a bottle of melatonin (which is a great help with my
insomnia) because a bunch of fools were using it to produce a relatively crummy psychadelic.
Case in point: I can no longer easily buy Sudafed (the *only* OTC drug I can buy that actually works for the sinus congestion and headaches I get
without untoward side effects... like insomnia), because a bunch of fools used the pseudoephedrine it contains to make methamphetamine.
Best of luck to you,

A quick look at Rhodium is all you could do?

Let's stick this in beginnings, then. In keeping with site policy, it is OK to ask questions about ANY type of chemistry.
Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

Destroy Melatonin?
Well maybe.
Indoles may, or may not, be fussy, depending on exact conditions.
A few years of reading on the subject, may clarify.
Processes that start with tryptophols are sometimes more favored by big pharma.

Might be beyond you at this point. But, there are several interesting articles therein.

You'd need a base like N,N-diisopropylethylamine or triethylamine to prevent formation of the quaternary amine. This is mentioned in the TIHKaL
reference you cited. It looks like the synthesis of the product, 5-MeO-DIPT is pretty well documented in the literature, so that's your best bet.
Here's a link referring to the hydrolysis of melatonin from Rhodium: Hydrolysis of Melatonin
Sodium dithionite is probably used to prevent oxidation of the product. Otherwise the reaction is a simple hydrolysis.

The role of the base is not to prevent overalkylation, its just a non-nuclephilic base that mops up protons without getting alkylated itself afaik.
Also there is no risk of overalkylation to the quartinary amine in this case because of the bulky isopropyl groups.

As I recall, Shulgin used hydrogenation of the Acetone Imine/Enamine to produce some Di-isopropyl Tryptamines. Steric hindrance was such, that
alkylation of the mono-isopropyl tryptamine, via isopropyl-chloride....didn't work very well.
Though I am having trouble finding the reference.
Well, maybe I'm just wrong. Can't find it.
