1. Į 1,00 g 2-jodobenzoinės rūgšties suspensiją 30 ml dichlormetano 0 *C temperatūroje lašiniu būdu įpilta 4,00 g oksalio chlorido.
2. Reakcijos mišinys buvo pašildytas iki kambario temperatūros ir maišytas 2 val.
3. Atvėsus, tirpiklis ir oksalichlorido perteklius buvo pašalinti vakuume ir gauta ruda liekana (0,90 g), kuri buvo panaudota kitame etape be tolesnio gryninimo.
4. 1,40 g indolo 5,0 ml eterio buvo lašiniu būdu įpilta į 0 *C temperatūroje maišytą 3,17 ml 2,5M etilmagnio bromido 2,5M eteryje tirpalą, atskiestą 1,1 ml eterio.
5. Tirpalas buvo maišomas 0,5 h kambario temperatūroje, po to lašiniu būdu buvo įpilta 0,90 g 2-jodobenzoilchlorido tirpalo 5 ml eterio.
6. Reakcijos mišinys buvo maišomas 1,5 h, gesinamas sočiu vandeniniu amonio chloridu ir maišomas tol, kol kietoji medžiaga suskilo į smulkią suspensiją.
7. Likutis buvo nuplautas vandeniu ir eteriu, po to suspenduotas 20 ml metanolio, į kurį pridėta 4 g natrio hidroksido ir 10 ml vandens.
8. Mišinys maišytas kambario temperatūroje 18 h, kietoji masė nufiltruota ir išplauta paeiliui metanolio, vandens ir eterio porcijomis.
9. Džiovinant vakuume 100 *C temperatūroje 1,06 g (70 %) 3-(2-jodobenzoil)indolo virto klampiu aliejumi, kuris buvo panaudotas kitame etape be tolesnio gryninimo.

1. Į 1,06 g 3-(2-iodobenzoil)indolo tirpalo 10,0 ml N, N-dimetilformamido įpilta 0,5 g natrio hidrato.
2. Reakcijos mišinys buvo maišomas kambario temperatūroje ir lėtai įpilta 1,03 g 1-bromo-5-fluoropentano.
3. Tirpalas buvo maišomas 120 *C temperatūroje 1 val.
4. Atvėsęs reakcijos mišinys buvo praskiestas vandeniu ir ekstrahuotas trimis etilacetato porcijomis.
5. Ekstraktai buvo nuplauti sūrymu ir išdžiovinti, o tirpiklis pašalintas vakuume.
6. Gauta 0,60 g (30 %) 1-(heptil-7-karboksilato)-3-(2-jodobenzoil)indolo kaip geltonos spalvos kietoji medžiaga.

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!
