Procedure

A mixture of (R)-2-(3-bromo-4-cyanophenylamino)-4-methylpentanamide (120 mg, 0.387 mmol), 3-amino-5-methylisoxazole (60 mg, 0.612 mmol), BINAP (40 mg, 0.064 mmol), Pd(OAc)2 (30 mg, 0.13 mmol) and K2CO3 (150 mg, 1.08 mmol) in dioxane (3 mL) was degassed with Ar, then was stirred at 120 C for 18 h. The mixture was concentrated in vacuo. The residue was purified by HPLC to give (R)-2-(4-cyano-3-(5-methylisoxazol-3-ylamino)phenylamino)-4-methylpentanamide (25 mg).
