with caesium carbonate;1,2-bis-(diphenylphosphino)ethane;bis(pinacol)diborane;copper dichloride in N,N-dimethyl-formamide at 45; for 15 h;
Steps:
III A process for preparing 4-nitro-4'-aminodiphenyl ether
To the 50 mL reaction flask, p-fluoronitrobenzene (7.06 mg, 0.05 mmol), pinacolate (22.86 mg, 0.09mmol), copper chloride (0.6811%, 10% * 0.05mmol) (3.98mg, 20% * 0.05 mmol), cesium carbonate (6.52 mg, 40% * 0.05 mmo 1). The reaction temperature was 45 ° C, reaction time was 15h, the resulting dark brown solution was dissolved in water and extracted with ethyl acetate. The ethyl acetate layer solution was retained, suspended, and then separated by a 200-300 mesh silica gel column (Eluent 1: 1 methylene chloride / n-hexane). Removal of the solvent gave 4-nitro-4'-aminodiphenyl ether of the formula:
