Reaktionsschritte
A mixture of tert-butyl (1S,2R)-2-(3-bromo-4-cyanophenylamino)cyclohexylcarbamate (150 mg, 0.380 mmol), 3,5-dimethylaniline (95 uL, 0.761 mmol), BINAP (40 mg, 0.064 mmol), Pd(OAc)2 (25 mg, 0.11 mmol) and K2CO3 (150 mg, 1.08 mmol) in dioxane (4 mL) was degassed with Ar, then was stirred at 100 C for 4 h. EtOAc and water were added. The organic phase was separated, washed with 1N HCl, then with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give tert-butyl (1S,2R)-2-(4-cyano-3-(3,5-dimethylphenylamino)phenylamino)cyclohexylcarbamate as a crude residue.
