Sarkate, A. P. published the artcileConvenient Microwave-Assisted Chlorosulfonic Acid-Catalyzed Synthesis of Some Quinazolinones from 2-Phenylindole, Quality Control of 6850-57-3, the publication is Russian Journal of Organic Chemistry (2022), 58(3), 428-432, database is CAplus.
A new convenient method was developed for the synthesis of quinazolinones from 2-phenyl-1H-indole and substituted amines under catalysis by chlorosulfonic acid. The target quinazolinones were synthesized through a coupling reaction of 2-phenyl-1H-indole and different amines using chlorosulfonic acid and hydrogen peroxide in DMSO on heating at 100°C, as well as under microwave irradiation at 80°C. The microwave-assisted synthesis provided excellent yields in 8 min compared to 4-5 h under conventional heating. The developed method is flexible and economical, and it has major importance in industry and academics.
Russian Journal of Organic Chemistry published new progress about 6850-57-3. 6850-57-3 belongs to ethers-buliding-blocks, auxiliary class Amine,Benzene,Ether, name is (2-Methoxyphenyl)methanamine, and the molecular formula is C8H11NO, Quality Control of 6850-57-3.
