Related Products of 886374-01-2 , The common heterocyclic compound, 886374-01-2, name is 5-Chloro-3-fluoro-2-methoxypyridine, molecular formula is C6H5ClFNO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
A stirred mixture of 5-chloro-3-fluoro-2-methoxypyridine (0.33 g, 2.0 mmol), bis(pinacolato)diboron (0.58 g, 2.3 mmol), [l,l-bis(diphenylphosphino)- ferrocene]palladium(II) chloride, complex with DCM (0.17 g, 0.21 mmol), and potassium acetate (0.61 g, 6.17 mmol) in dry 1,4-dioxane (8.0 mL) was purged three times with argon and placed under vacuum three times. The mixture was heated to and monitored with LC-MS and TLC. After 21 h, the reaction was cooled to rt then filtered through Celite. The organic solvent was removed under reduced pressure, and the black residue was identified as 3-fluoro-2- methoxy-5-(4,4,5,5-tetramethyl-l ,3,2-dioxaborolan-2-yl)pyridine and used without purification. Mass Spectrum (pos.) m/e: 254.0 (M+H)+.
The synthetic route of 886374-01-2 has been constantly updated, and we look forward to future research findings.
