I am for sure going to try this, will read in detail when I get home.
I realised I’m going to have a fair bit of ethylenediamine left over after running out of 2,5-DMOBA, and this allows you to use less nitromethane than the synth I follows - that’s the real bottle neck so yeah. Interesting!
Damnit - I keep losing my original threads and then making a new one…then just as I’m either doing the reaction or just after iv made a new thread someone comments on the old one!!
Anyway - I seem to have had quite a successful time to be honest. This was the heaviest weigh tray iv put into the...
That’s very interesting and useful info indeed!!
People’s timing on this forum seems to be really on point!
Last time someone gave me their 2,5-DMOBA-> b-2,5-DMONS right on the day I needed it and it worked really well….
Now this time, I literally tried the other (ammonium acetate) route...
Okay so…
Today I decided I wanted to do a Henry condensation, this time on 3,4,5-TMOBA.
So I figured, why not start with Shulgin’s method - only I didn’t really want to commit to 20g of aldehyde and so I halved everything.
I was super surprised that after around 1.5h it started getting pretty...
Oh how interesting. Yeah iv seen the heat gun used before but mainly for getting (mostly THC) out of the collection flask after it goes all goopy.
It makes sense to try and use it to stop clogging yeh.
Nice one @FENTAMAS for allowing me to learn but also pointing me exactly where to go to do...
That is BEAUTIFUL chemistry but so far removed from the easy, low temperature reductive amination from tryptamine, using the relevant aldehyde….
Still though, it’s pretty incredible to see what you had to go through if you wanted to try any of these before this low temperature reaction was...
I have two questions….from your DM.
1. Did you make a methanol/acetaldehyde solution to add to the addition funnel to make it less reactive meaning better temp control and less evaporation?
2. In your workup, I assume the K2CO3 was used to make the solution basic before you extracted? Could...
Sorry yeah, I meant the original tryptamine, I actually ended up having quite good results using ethyl acetate to re-x from….it went from small opaque/tan/yellow small crystal to a larger translucent ‘sugary’ looking crystals.….and why? Just to ensure purity before doing the diethylation, as...
Interesting as I literally just ordered a short path distillation head!
Yes I’m not talking about the nitrostyrene’s iv had good success following your techniques re-that.
It’s more me just trying to ensure as effective reaction as possible really and trying to maximise yield.
Yeh that is what...
@FENTAMAS Hey sorry, one last question…
what did you re-x your 2,5-DMOBA from to start? It seemed really soluble in methanol, I was thinking maybe some methanol and water? If you know of a better mix, please do tell…
I just tried to do a re-x of the b-2,5-DMONS from methanol first but it...
@FENTAMAS
I just wanted to say thanks for stressing the importance of re-crystallisation of reagents before starting your reactions.
I have come to realise the tryptamine I was working with wasn’t particularly pure because it’s now massive crystals that are white instead of like dirty...
Pretty much all in the title for my next low temperature reductive amination to other psychedelic tryptamines…n,n-DET, this time but that’s not really the point.
I’m also wondering if I should just salt some out in order for it to store better. Maybe as the benzoate? Think it was that one that...
Yeah. I realised a dude is selling cyclohexylamine hydrobromide - so that SHOULD be fairly straight forward to obtain the freebase from for catalysis of 3,4,5-TMOBA , of which I have 500g coming this week.
i just hope it will be pure enough to give me a good product for catalysis…should I do a...
Okay smashing…
im assuming I didn’t keep it cold enough last time and got a b-carboline side product or something instead.
This is a reaction I have been meaning to come back to actually…
I ran the reaction and have basically been both, working on another reaction in the meantime (a...
Ooo that’s interesting…
I do actually plan to try and make some cyclohexylamine…
I was going to try make a video about it given there are none on YouTube - I was surprised by this tbh…if I can actually get it to work that is lol
We’ll see but if not I can just buy it in for when my...
Yeah people keep saying that but I sided all my nitromethane from the EU and distilled it from a 40%w/w nitromethane;DCM mix, worked great for making b-2,5-DMONS.
The issue for me is finding each relevant catalyst for each aldehyde I want to perform the Henry reaction on….
I was thinking about...
