Reference of 58534-95-5, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 58534-95-5, name is 3-Bromo-2-fluoroaniline belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A mixture of 3-bromo-2-fluoro-phenylamine (6.52 g, 33.63 mmol), bis(pinacolato)diboron (10.45 g, 41.14 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(ll), complex with dichloromethane (1 :1) (1.12 g, 1.37 mmol) and potassium acetate (10.1 g, 103.06 mmol) in dry DMF (65 mL) was heated at 100C under an atmosphere of nitrogen for 7 hours. The reaction was allowed to cool to room temperature, diluted with AcOEt and filtered through celite. The organic was washed with water, brine, dried over Na2SO4 and evaporated. The crude was purified by silica gel chromatography which was eluted with hexane:AcOEt = 8:2 to afford 2-fluoro-3-(4,4,5,5- tetramethyl-[1 ,3,2]dioxaborolan-2-yl)-phenylamine (6.90 g) as white solid.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3-Bromo-2-fluoroaniline, other downstream synthetic routes, hurry up and to see.
