Reaction Steps

A mixture of (R)-2-(3-bromo-4-cyanophenylamino)-4-methylpentanamide (187 mg, 0.603 mmol), 5-amino-3-methylisothiazole hydrochloride (115 mg, 0.763 mmol), BINAP (40 mg, 0.064 mmol), Pd(OAc)2 (30 mg, 0.13 mmol) and K2CO3 (300 mg, 2.17 mmol) in dioxane (4 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-(3-methylisothiazol-5-ylamino)phenylamino)-4-methylpentanamide (102 mg).
