Electric Literature of 4403-36-5, The chemical industry reduces the impact on the environment during synthesis 4403-36-5, name is 2-(1,3-Dioxoisoindolin-2-yl)ethanesulfonylchloride, I believe this compound will play a more active role in future production and life.
To 3-exo-[(S)-1-((S)-2-methyl-propane-2-sulfinylamino)-2-(2,4,5-trifluoro-phenyl)-ethyl]-8-aza- bicyclo[3.2.1]octane (540 mg, 1.2 mmol) in dichloromethane/1 M NaOH (1/1, 5 mL) is added 2-phthalimidoethane sulfonyl chloride (1.101 g, 3.59 mmol) then the resulting mixture is stirred at 500C during 16h. It is extracted with dichloromethane, the organic phase is dried and evaporated to give a white solid. MS: 626 [M+H]+HPLC (Zorbax SB C18, 2min method (0-0.8min 10-95%ACN, 0.8-1.5min 95%ACN, 1.5- 1.6min 95-10%ACN, 1.6-2min 10%ACN): 1.44 min.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-(1,3-Dioxoisoindolin-2-yl)ethanesulfonylchloride, other downstream synthetic routes, hurry up and to see.
