Ethyl acetate, it just needs some trick to get, but it’s worth it, a expert of BB - WillD recommended triethylanime, he post video about it too

It means you can buy ma solution directly, as I said in the beginning, I use ma.hci, so NaOH would be used in my synthesis, and NaOH would have bad reaction with DCM

you can find answer on other experts from here, if you just got benzene or DCM ( I know it is easy to get )just don’t do this synthesis and just don’t listen to this post, you re just wasting your materials and times

I finally succeeded two weeks ago, I figured out the critical part is the solvent in the beginning, DCM and benzene are just terrible for this synthesis

Which seller you recommended ? Or you recommend us to synthesis ourselves?

I used benzene is because I saw another synthesis can apply it as solvent, and ethyl acetate is ban in my city; about the ratio of methylamine is because I watched another article about 1 mole of 2b4m combine 1 mole of methylamine can form 1 mole of 4-mmc, but what I have is MA.HCI, so 400g of...

First of all, I use benzene 1 L to dissolve 500g of 2b4m, and it can’t dissolve completely at the beginning, so I heat it up a little until it dissolves, after that, the solution is warm but not boiling. I used 10L round bottom flask 2. I prepare the NaOH aq solution (300g of NaOH and 600ml...

May I have a question about the ma.HCI part ? I’ve watched your post about adding ma.HCI directly into the mixture, and I also try it once recently, I have a problem when I dissolved the 2b4m in solvent, should I followed with NaOH + water and start stirring, then adding MA.HCI immediately with...

Because I have a condition that I do not have any lab equipment this time, I only have plastic box, bucket, cup and a fridge, so the process of making MA.solution 40% from MA.HCI is very hard for me to accomplish, I hope i can have some professional advice.

Sorry, it is type error, what I have is cas 593-51-1; after read your opinion, can i basically only use water to dissolve cas 1451-82-7, then adding NaOH in water, mixed it together first, then slowly adding MA.HCI into the RM and stir, the whole process should be under 30 Celsius and sealed...

I just make it once, I make methylene solution myself, I used cold distilled water for it, then I add it to 2b4mp with benzene, somehow I already can see the separation of layers, anyone can help me ? Because I wash it with water on next step, eventually the outcome is so little, I’m afraid the...

What you want ? You want a partner or an address for receiving or any other method you preferred

Then why don’t you try it instead?

Yes, if you start from 102-01-2, the most advanced way to make the final product takes 3 weeks

You mean followed this post completely could reach such high yield or there’s any trick ? I just still has a little confuse about the NMP, after the methylation, should I acidify it immediately or adding NMP is necessary part ? If it’s necessary, then what it does to the synthesis ? I just...

Does anyone making a higher yield from this synthesis ?

Forgive my ignorance, the part that ‘there was a long induction period and then the yield was low. This behavior could be obviated by reducing the catalyst first and then adding the reactants. ‘ I just don’t get it how to obviate the long induction period by reducing the catalyst, the catalyst...
