1. solis:
8CyNU5m0HG

1. 1,00 g 2-jodobenzoskābes suspensijai 30 ml dihlormetāna 0 *C temperatūrā pilienveidīgi pievieno 4,00 g oksalila hlorīda.
2. Reakcijas maisījumu uzsildīja līdz istabas temperatūrai un maisīja 2 h.
3. Pēc atdzesēšanas šķīdinātāju un lieko oksalila hlorīdu atdalīja vakuumā, iegūstot brūnu atlikumu (0,90 g), ko izmantoja nākamajā posmā bez tālākas attīrīšanas.
4. Maisītam 3,17 ml 2,5 M etilmagnija bromīda 2,5 M etilmagnija bromīda šķīdumam ēterī, atšķaidītam ar 1,1 ml ētera, 0 *C temperatūrā pa pilieniem pievienoja 1,40 g indola 5,0 ml ētera.
5. Šķīdumu 0,5 h maisīja istabas temperatūrā, un pēc tam pilienu pa pilienam pievienoja 0,90 g 2-jodobenzolsilhlorīda šķīdumu 5 ml ētera.
6. Reakcijas maisījumu maisīja 1,5 h, nodzēsa ar piesātinātu ūdens amonija hlorīdu un maisīja, līdz cietā viela sadalījās smalkā suspensijā.
7. Atlikumu mazgāja ar ūdeni un ēteri, pēc tam suspendēja 20 ml metanola, kam pievienoja 4 g nātrija hidroksīda un 10 ml ūdens.
8. Maisījumu maisīja istabas temperatūrā 18 h, cieto vielu filtrēja un izskaloja ar secīgām porcijām metanola, ūdens un ētera.
9. Pēc žāvēšanas vakuumā 100 *C temperatūrā 1,06 g (70 %) 3-(2-jodobenzoil)indola ieguva viskozu eļļu, ko izmantoja nākamajā posmā bez tālākas attīrīšanas.


2. posms:
4RXODjV1Hx

1. 1,06 g 3-(2-jodobenzolsil)indola šķīdumam 10,0 ml N, N-dimetilformamīda pievienoja 0,5 g nātrija hidrāta.
2. Reakcijas maisījumu maisīja istabas temperatūrā un lēnām pievienoja 1,03 g 1-brom-5-fluoropentāna.
3. Šķīdumu maisīja 120 *C temperatūrā 1 h.
4. Pēc atdzesēšanas reakcijas maisījumu atšķaidīja ar ūdeni un ekstrahēja ar trim etillacetāta porcijām.
5. Ekstraktus mazgāja ar sālījumu un nosusināja, un šķīdinātāju atdalīja vakuumā.
6. Iegūst 0,60 g (30 %) 1-(heptil-7-karboksilāta)-3-(2-jodobenzoil)indola kā dzeltenu cietu vielu.

The synthesis says it makes 1-(heptyl-7-carboxylate)-3-(2-iodobenzoyl)indole, but it should be 1-(5-fluoropentyl)-3-(2-iodobenzoyl)indole (AM-694) based on 1-bromo-5-fluoropentane. No way that reagent adds a heptyl or carboxylate group. Looks like a mix-up—can you clarify the synthesis path?
Thanks

I also have seen such misslabelings in chemicals that comed as synthetic canabinoids, on the image path all is clear but the think im seeing is the canabinoids that come from china was euphoric and strong, and now all this canabinoids made by this way or by kits are actualy less euphoric then thc, im almost shure here is a big lie that we normal people dont know, but from where comes the difference ?

If synthetic cannabinoid is weaker than THC, then it was synthesized with errors. The JWH series is much stronger than THC, maybe it's not always more euphoric, but many people like the powerful action of synthetics. Still, THC is milder.

I remember when taking the first china adb-butinaca, 5f-sgt-151,am-2201, and some other i have tried from china and they were actualy so euphoric like third eye happines/euphoria 8/10 euphoria 8/10 sedation(thry were china stock but shiped from spain buyjwh if you remember them, and i tried the greece flyrc products first and was so disapointed, and recently tried a 5f i think, and that was not only not strong, but and making me feel so bad, normal thc is 5/10 euphoria and 3/10 sedation lets say for me when i dont have tolerance and all the newer ones made by the chinese precursors are so weak and i cant figure out why just zero euphoria, thats not how canabinoids are supposed to fell from my experience, i still havent tried to made a canabinoid but im a big enthusiast of FC or grignard so i must try haha

@HIGGS BOSSON The synthesis claims to produce 1-(heptyl-7-carboxylate)-3-(2-iodobenzoyl)indole, but it should actually result in 1-(5-fluoropentyl)-3-(2-iodobenzoyl)indole (AM-694) using 1-bromo-5-fluoropentane. It's unlikely that this reagent would introduce a heptyl or carboxylate group. It seems like there might be a mix-up—could you clarify the synthesis route? Thank you!
