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%).

Înmulțiți totul cu 370x (1000g/0,37g = 370 raport) ca "regulă de bază".

Desigur, sunt sigur că unii solvenți permit un amestec cu densitate mai mare, de exemplu, nu aveți nevoie de 370x mai mult acetat de etil, dar observați rapid când soluția este suprasaturată, dar rețineți că mai multă căldură permite o saturație mai mare (nu sunt sigur de ce).

Mulțumesc pentru asta, apreciez. Dar sunt novice și am nevoie de informații specifice pentru a evita greșelile.

Poate cineva să încarce un tutorial video? Sunt începător și nu vreau să știu fiecare pas (inclusiv echipamentul necesar). Aș fi recunoscător, mulțumesc mult

Bună ziua, acesta este analogul 5F-CUMYL-PEGACLONE (5F-SGT-151)?
Intenționați să încărcați și o sinteză a acestuia? Ar fi mai mult decât interesant.
Vă mulțumim pentru munca dvs. extraordinară.

Tocmai mi-am dat seama că baza 5F-SGT-151 conține și un al treilea inel benzenic. Încărcarea nomenclaturii.
Mă întrebam dacă 5F-SGT-151 ar putea fi creat și în loc de 1-bromo-5-fluoropentan folosit ca coadă,
am putea folosi 1-bromo-6-fluorohexan. Ne-ar oferi acest lucru o afinitate / efecte și mai mari ale receptorului?

Conform acestor date, aș spune că da, dar este doar o ipoteză.

Da, cred că va fi suficient. Mai am o întrebare. Care este cel mai puternic canabinoid?

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