Και τα δύο λειτουργούν και τα δύο είναι καλά.

Hi Marvin
Great video and I have successfully synthesized 4mmc using this synthesis, thanks. Worked beautifully when acidified with hcl35 but using hbr48 turned out to be a disaster..is hbr not interchangeable with hcl for acidification of 4mmc in benzene?

C10H11BrO + CH5N → C11H15NO + HBr
Όπως φαίνεται από την εξίσωση, ένα μόριο 2-βρωμο-4-μεθυλοπροπιεοφαινόνης παράγει ένα μόριο μεφεδρόνης.
C10H11BrO : 227,0977 g/mol
C11H15NO : 177.2429 g/mol
227.0977/177.2429=1.28127953
Ο συντελεστής είναι 1,28127953
Αυτό σημαίνει ότι από 100g 2-βρωμο-4-προπιφαινόνης, θα λάβετε 78,0469818g βάσης μεφεδρόνης.

Η μάζα της υδροχλωρικής μεφεδρόνης θα αυξηθεί κατά 1,19 g/cm3 και ο συντελεστής θα είναι 1,27273446
C11H15NO+HCl=177.2429+1.19=178.4329
227.0977/178.4329=1.27273446

100g(C10H11BrO)/1.27273446=78.5709849g(C11H15NO)
Η θεωρητική απόδοση της αντίδρασης της 2-βρωμο-4-μεθυλοπροπιεοφαινόνης ήταν 78,5709849g υδροχλωρικής μεφεδρόνης. Θα πρέπει όμως να ληφθεί υπόψη ότι είναι δύσκολο να επιτευχθεί η θεωρητική απόδοση, συνήθως η απώλεια είναι 20%.

Βρήκα έναν προμηθευτή υγρού 2-Bromo-4-Methylpropiophenone αλλά δεν ξέρω πώς να ξεκινήσω από αυτό το σημείο και πόσο υγρό πρέπει να χρησιμοποιήσω για να φτιάξω 100g 4mmc. χρειάζομαι κάποιες συμβουλές.

Δεν είναι ποιοτικά καθαρισμένο ή λίγος χρόνος για την αντίδραση. Χρειάζονται περισσότερες λεπτομέρειες.

Greetings

4mp to 4mmc successfully this way for me but starting 4mp was yellow so bromination done as per process.

Resultant mephedrone was a pasty powder and not crystal like salt as in video. Power was also low even after crystallization. Any thoughts on the pasty powder and low power. Yield was about 120 gms recrystallized from 400 ml 4mp.

Is there any way to purify the 4mp we get to start with or is that fine?

Would a superior product be possible if 4mp is brominated using NBs and PTSA, purified with a solvent nd then make the nmp synthesis from that 2b4m?

Thanks in advance. Tc

Δεν πρόσθεσα ακετόνη, μόνο MMC freebase σε βενζόλιο, και έριξα 30% HCl σε pH 5,5. Πρόσθεσα το οξύ αργά. Θα μπορούσε να είναι η ακετόνη το πρόβλημα; Το ξέχασα, γιατί συνήθως κάνω οξίνιση με DCM+νερό, οπότε η ακετόνη δεν μου ήρθε στο μυαλό. Πώς οξίνισες την ομορφιά της φωτογραφίας; Σας ευχαριστώ πολύ.

Εάν χρησιμοποιείτε aq. υδροχλωρικό οξύ, χρειάζεστε έναν διαλύτη που δεσμεύει το νερό. Αυτός είναι η ακετόνη ή η αλκοόλη (αιθανόλη, προπανόλη)

Awesome tutorial!

I have question. Can be this tutorial used for 3-CMC or 3-MMC?

I'm using 2-bromo-4-methylpropiophenone for 4-MMC. What to use for 3-MMC?

@Marvin "Popcorn" Sutton can we scale this up using a 50litre batch reactor and drop the bromine Benzene mix from the reactors dropping funnel without any issues?
Bromine mix in an enclosed dropping funnel is a litle scary
