Reaction Steps
A mixture of tert-butyl (1S,2R)-2-(5-bromo-4-cyano-2-fluorophenylamino)cyclohexylcarbamate (165 mg, 0.400 mmol), 5-amino-3-phenylisoxazole (96 mg, 0.600 mmol), sodium phenoxide trihydrate (136 mg, 0.800 mmol), xantphos (30 mg, 0.051 mmol) and Pd2(dba)3 (30 mg, 0.032 mmol) in dioxane (2 mL) was degassed with Ar, then was heated at 170 C for 30 min by microwave. It was concentrated in vacuo. The residue was purified by HPLC to give tert-butyl (1S,2R)-2-(4-cyano-2-fluoro-5-(3-phenylisoxazol-5-ylamino)phenylamino)cyclohexylcarbamate (40 mg).
