Reaction Steps

A mixture of (R)-2-(3-bromo-4-cyanophenylamino)-4-methylpentanamide (120 mg, 0.387 mmol), 5-amino-3-methylisoxazole (60 mg, 0.612 mmol), sodium phenoxide trihydrate (100 mg, 0.588 mmol), xantphos (25 mg, 0.043 mmol) and Pd2(dba)3 (20 mg, 0.021 mmol) in dioxane (3 mL) was degassed with Ar, then was heated at 170 C for 15 min by microwave. It was concentrated in vacuo. The residue was purified by HPLC to give (R)-2-(4-cyano-3-(3-methylisoxazol-5-ylamino)phenylamino)-4-methylpentanamide (20 mg).
