실험 절차

A solution of 2-bromo-4-fluorobenzonitrile (0.761 g, 3.80 mmol), tert-butyl (1S,2R)-2-aminocyclohexylcarbamate (1.00 g, 0.808 mmol) and DIEA (1.00 mL, 5.76 mmol) in DMSO (6 mL) was stirred at 100 C for 18 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-(3-bromo-4-cyanophenylamino)cyclohexylcarbamate (1.48 g) as an off-white solid.
