Modern MDA. How do you make MDA from helional?

I am achieving 60% yield in the synthesis of MDA Helional + Hydroxylamine. The best way for large-scale production.

kamikaze3030There is no fucking way you, or anyone, is getting 60% overall yields on this entire scheme from helional to MDA. This place is a shitshow. I can do consults, and would be willing to for the right price. Maybe a mod can help me help these lost fellows.

Hello friends. I have a question
1. In the final step, you use the crystallization method with a stream of HCl gas. Is that right or does it burn?

2. Amide.

100 g aldoxime is mixed with 300 mL xylene and 2 g nickel acetate, added and refluxed for 5 hours. Distill approximately 100 mL xylene and allow the mixture to cool. Amide approximately 70. The grams are separated and filtered and dried. Can be recrystallized with xylene.
=How much heat can you give?
3. Aldoxime.
If aldoxime does not harden Add more hydroxylamine and base.
How much hydroxylamine and base should I add?

thank you

I don't do it that way, friend. I'm doing it differently, totally different.

kamikaze3030Hello friend, what do you use?
What method is used to synthesize MDA?
Could you please tell me? about the synthesis process and details of your chemicals

HIT MONKEYYes, I succeed. It is the best method to do it on a large scale. Simple and efficient. Few easily accessible equipment and supplies.

kamikaze3030Hello friend, I have a question.
In the last step you just use
(NaOH) in case it crystallizes, right?
And the .PH value should be 7.5, right?
I don't know much about chemistry.
If I'm going to confess, it's that I don't know. After adding the substance (NaOH), what must be done to get MDA? I want to ask you Can you tell me?

HIT MONKEYMy method is different from yours. I don't do it that way.
