934240-59-2, name is 1-((4-Bromophenoxy)methyl)-2-fluorobenzene, belongs to ethers-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: 934240-59-2
To a stirred suspension of magnesium metal (9Og) in dry THF (60OmL) under a nitrogen atmosphere at room temperature was added iodine (0.3g). The mixture was heated to an internal temperature of 64 +/- 2C. A solution of 1-[(4- bromophenoxy)methyl]-2-fluorobenzene (693g) in THF (150OmL) was added in two batches. Firstly 45 mL was added. Secondly, the remaining solution (1455 mL) was added dropwise. After addition, the reaction was heated at reflux for 1 h. The reaction mixture was cooled to room temperature. This reaction mixture was then added slowly to a solution of commercially available 1-te/t-butyl 2-methyl (2S)-5-oxopyrrolidine-1 ,2- dicarboxylate (30Og) in THF (150OmL) cooled to -6O0C, maintaining the internal temperature below -600C. The addition was completed in 2 hours. The reaction mixture was stirred for a further 15 minutes after addition, lsopropyl alcohol (30OmL) was then added dropwise whilst maintaining the temperature below -600C. A mixture of aqueous saturated ammonium chloride solution/aqueous saturated sodium chloride solution (2/1 ;
The synthetic route of 934240-59-2 has been constantly updated, and we look forward to future research findings.
