Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 179898-34-1, name is 3-Bromo-5-fluorobenzonitrile, This compound has unique chemical properties. The synthetic route is as follows., category: nitriles-buliding-blocks
2-Phenyl-4,5,6,7-tetrahydrooxazolo[5,4-c]pyridine hydrochloride (purchased from Anichem) (150mg, 0.63 mmol), tris(dibenzylideneacetone)dipalladium(0) (40 mg, 0.04 mmol), BINAP (97 mg, 0.16 mmol) and 3-bromo-5-fluorobenzonitrile (126 mg, 0.63 mmol) were combined in toluene (3 mL). The mixture was first flushed with nitrogen before and after the addition of sodium tert-butoxide (73 mg, 0.76 mmol). The solution was heated at 1200C under nitrogen overnight. The solvent was concentrated and removed under vacuum. The residue was then purified by silica gel column (EtOAc (10% MeOEta)/hexanes), followed by recrystallization in methanol to give a white solid (10 mg, 5%). 1H NMR (400 MHz, CDCl3): delta 8.01 (m, 2H), 7.46 (m, 3H), 6.97 (s, IH), 6.81-6.85 (m, IH), 6.78 (m, IH), 4.32 (m, 2H), 3.77 (t, 2H), 2.95-2.98 (m, 2H); LC/MS: m/e = 320 (M+H)+.
According to the analysis of related databases, 179898-34-1, the application of this compound in the production field has become more and more popular.
