Anyone here tried making 2,5-dimethoxybenzaldehyde using benzaldehyde and pyridine?

Pretty much all in the title but if you have, can you give me an idea of how easy it is?
I have a load of benzaldehyde and I’m not into amphetamine’s very much, I would much rather convert it to 2,5-dmobzh (yes that’s my shorthand for the above chem lol) and risk getting half the amount of final product as it’s doubly useful to me!
also benzaldehyde is really easy to get and so if it’s a relatively do-able synth then I think I’m onto something and can start following some 2c recipes.
any thoughts or troubles I may face? I don’t NEED a kilo of it…
Even 250g seems excessive to me but whatever, I’m not a seller

Sorry I meant the 3,4-trimethoxybenzaldehyde

At least I could make mescaline in small quantities….

from 4-methoxybenzaldehyde u can do. But it is better to buy end material in our listing, it will be cheaper.

If you have to ask this question it means you won't. It's not clear to you why, but you will end up buying or receiving some. Maybe approach vanillin with 3,4,5-(MeO)3-BA in mind rather than 2,5-(MeO)2... tried from p-anisaldehyde and the work is tough.

Yeah I learnt. I realised like 5 mins after I posted this I meant something like 3,4-hydroxy ph or something, got confused between the mescaline precursor, the 2c main precursor and 3,4hydroxyphenrthylamine. Totally different
…sorry about that. Iv since had a lesson on phenethylamines and the way in which you essentially read chemicals backwards so the 3 and 4 position are totally wrong, not to mention hydroxy instead of dimethoxy or trimethoxy. Sorry about that!

Wow it’s really interesting to have all my super old nonsense posts dragged up again since the annoying re-design of the forums!
Makes me look stupid - which I probably am but at this stage I was / am learning!
I quickly found buying precursors to be of great value

I am studying myself, I thought the 2,5 dimeobenz was for making 2cb and the 345trimeobenz was for mescaline and tma.

I think someone posted that the anise oil to 2,5dimethoxybenzaldehyde wouldn't work, which sucks, because fennel grows wild along I5 and hwy 101 for hundreds of miles, from southern cal to Washington, and can be extracted like BHO with butane

 

[Rabidreject]

Yeah you are right - hence my sarcastic comment above at how little I knew back then…

 

[Rabidreject]

As I said, I quickly worked out just buying them to be a hell of a lot easier!
Now alkylation of 2,5-DMOBA, at the 4 position is something I am interested in now…
