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%).

Kerro vain kaikki 370x (1000g/0,37g = 370 suhde) "perussääntönä".

Tietenkin olen varma, että jotkut liuottimet mahdollistavat suuremman tiheyden seoksen esim. et tarvitse 370x enemmän etyyliasetaattia, mutta huomaat nopeasti, kun liuos on ylikyllästetty, mutta pidä mielessä, että enemmän lämpöä mahdollistaa enemmän kyllästymistä (en ole varma miksi).

Voiko joku ladata opetusvideon? Olen aloittelija ja en halua tietää jokaista vaihetta (mukaan lukien tarvittavat laitteet). Olisin kiitollinen kiitos paljon

Hei, onko tämä analogi 5F-CUMYL-PEGACLONE (5F-SGT-151) ?
Aiotteko ladata myös sen synteesin? Se olisi enemmän kuin mielenkiintoista.
Kiitos valtavasta työstäsi.

Tajusin juuri, että 5F-SGT-151:n pohja sisältää ja kokonaisen kolmannen bentseenirenkaan. Nimikkeistön lataaminen.
Mietin, voisiko 5F-SGT-151:n valmistaa ja käyttää häntänä 1-bromi-5-fluoripentaanin sijasta 1-bromi-5-fluoripentaania,
voitaisiin käyttää 1-bromi-6-fluoriheksaania. Saisimmeko näin vielä suuremman reseptori-affiniteetin/vaikutuksen?

Kyllä, uskon, että se riittää. Minulla on vielä yksi kysymys. Mitkä ovat vahvimmat kannabinoidit?

Haloo,
Onko pyridiini vaihtoehto kalium-tert-butoksidille tässä reaktiossa?

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