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%).

Multiplicera bara allt med 370x (1000g/0,37g = 370 ratio) som "grundregel".

Naturligtvis är jag säker på att vissa lösningsmedel tillåter högre densitetsblandning, t.ex. behöver du inte 370x mer etylacetat men du märker snabbt när lösningen är övermättad men kom ihåg att mer värme tillåter mer mättnad (inte säker på varför).

Tack för det jag uppskattar det. Men jag är nybörjare och jag behöver specifik information för att undvika misstag.

Hej, är den här analogen till 5F-CUMYL-PEGACLONE (5F-SGT-151)?
Har du för avsikt att ladda upp en syntes av det också? Det skulle vara mer än intressant.
Tack för ditt enorma arbete.

Åh, jag insåg just, basen av 5F-SGT-151 innehåller och en hel 3: e bensenring. Laddar upp nomenklatur.
Jag undrade om 5F-SGT-151 kunde tillverkas och istället för 1-brom-5-fluoropentan användas som svans,
kunde vi använda 1-brom-6-fluorhexan. Skulle detta ge oss ännu större receptoraffinitet / effekter?

Enligt dessa uppgifter skulle jag säga ja, men det är bara en hypotes.

Ja, jag tror att det kommer att räcka. Jag har en annan fråga. Vilka är de starkaste cannabinoiderna?

Hallå där,
Är pyridin alternativ till kalium tert butoxid i denna reaktion?

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