501-00-8, name is 2-(3-Fluorophenyl)acetonitrile, belongs to nitriles-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. name: 2-(3-Fluorophenyl)acetonitrile
The reactor was charged with palladium(II) acetate (0.160 g, 0.71 1 mmol), 2,8,9-triisobutyl- 2,5,8,9-tetraaza-l-phosphabicyclo[3.3.3]undecane (0.507 mL, 1.421 mmol), and 5-bromo-2- methyl- lH-benzo[d]imidazole (1.5 g, 7.1 1 mmol). The vessel was evacuated and refilled with N2 for 3 cycles and degassed dioxane (14.21 mL) was added, followed by NaHMDS (28.4 mL, 28.4 mmol). The reaction was stirred at 25C for 20 min before 2-(3-fluorophenyl)acetonitrile (73.3 mg, 0.543 mmol) was added. The reaction was then capped and heated at 100C for 3 h. More NaHMDS (6 mL) was added and the reaction was stirred for another 1 h; More NaHMDS (4 mL) was added and the reaction was stirred for another 1 h before it was cooled to room temperature, and quenched with water. The aqueous layer was extracted with EtOAc (3x), washed with brine, dried over MgS04, filtered, and the filtrate was concentrated in vacuo. The crude material was purified by chromatography on silica gel (eluent: 0-100% A in B. A: 10% MeOH in DCM; B: DCM.). LCMS calc. = 266.10, found = 266.04 (M+H)+.
The synthetic route of 501-00-8 has been constantly updated, and we look forward to future research findings.
