Reaction scheme:
0x58bGwhPS

Synthesis:
1. A solution of 1H-pyrrolo[2, 3-b]pyridine-3-carboxylic acid (0.49 g, 3 mmol), oxalyl chloride (0.6 mL, 7.2 mmol), and DMF (1 mL) in dichloromethane (20 mL) was stirred for 20 min.
2. The mixture was evaporated and then redissolved in methanol (20 mL) and stirred for 40 min.
3. The mixture was evaporated and then extracted with ethyl acetate.
4. The organic phase was washed with saturated sodium bicarbonate solution and dried with Na2SO4, and the solvent was removed in vacuo to yield the white solid (0.36 g, 68%).
5. A solution of Step 4 (0.36 g, 2 mmol), potassium t-butoxide (0.27 g, 2.4 mmol), and 1-bromo-5-fluoropentane (1.6 g,9.5 mmol) in THF (20 mL) was stirred for 24 h.
6. The mixture was extracted with ethyl acetate.
7. The organic phase was washed with brine and dried with Na2SO4, and the solvent was removed in vacuo.
8. The residue was purified by silica gel chromatography with stepwise gradient elution of n-hexane/ethyl acetate (3:1–2:1–1:1, v/v) to yield the white solid (0.35 g, 65%).
9. A solution of step 8 (0.35 g, 1.3 mmol) and 6 mol/L sodium hydroxide solution (10 mL) in methanol/THF (2:1,v/v, 15 mL) was stirred for 1.5 days.
10. The mixture was evaporated, added to water, and then washed with ethyl acetate.
11. A solution of 1 mol/L hydrochloric acid was added to the aqueous phase, and the mixture was extracted with ethyl acetate.
12. The organic phase was washed with brine and dried with Na2SO4, and the solvent was removed in vacuo to yield the white solid (0.39 g, quant.)
13. A solution of step 12 (0.39 g, 1.3 mmol), oxalyl chloride (3 mmol), and DMF (1 mL) in dichloromethane (12 mL) was stirred for 10 min.
14. The mixture was evaporated and then redissolved in dichloromethane (10 mL).
15. Cumylamine (2 mmol) and triethylamine (0.5 mL) were added to the solution and stirred for 15 h.
16. The mixture was evaporated and then extracted with ethyl acetate.
17. The organic phase was washed with 0.1 mol/L hydrochloric acid solution, saturated sodium bicarbonate solution and brine, and then dried with Na2SO4, and the solvent was removed in vacuo to yield the white solid (0.37 g, 77%).

"Alapszabályként" egyszerűen szorozzon mindent 370x (1000g/0,37g = 370 arány).

Természetesen biztos vagyok benne, hogy egyes oldószerek nagyobb sűrűségű keveréket tesznek lehetővé pl. nem kell 370x több etil-acetát, de gyorsan észreveszi, ha az oldat túl telített, de ne feledje, hogy a nagyobb hő nagyobb telítettséget tesz lehetővé (nem biztos, hogy miért).

Köszönöm, hogy ezt nagyra értékelem. De im újonc, és szükségem van konkrét információkra a hibák elkerülése érdekében.

Tud valaki feltölteni egy oktatóvideót? Újonc vagyok, és nem akarom tudni minden lépést (beleértve a szükséges felszerelést is). Én lennék hálás köszönöm sokat

Helló, ez az analóg az 5F-CUMYL-PEGACLONE (5F-SGT-151) ?
Szándékában áll feltölteni egy szintézist is róla? Több mint érdekes lenne.
Köszönöm a hatalmas munkádat.

Ó, most jöttem rá, hogy az 5F-SGT-151 bázisa tartalmaz és egy egész 3. benzolgyűrűt. Nómenklatúra feltöltése.
Azon gondolkodtam, hogy az 5F-SGT-151-et meg lehetne-e alkotni, és az 1-brom-5-fluoropentán helyett farokként használni,
használhatnánk 1-brom-6-fluorhexánt. Ez még nagyobb receptoraffinitást/hatást eredményezne?

Ezen adatok alapján azt mondanám, hogy igen, de ez csak egy hipotézis.

Igen, azt hiszem, ez elég lesz. Van még egy kérdésem. Melyek a legerősebb kannabinoidok?

Halló!
A piridin alternatívája a kálium-tert-butoxidnak ebben a reakcióban?

I am interested in the synthesis of 5F-adb is there a simple reliable recipe?
