Reaction Steps

A mixture of (R)-3-(4-(1H-imidazol-1-yl)phenyl)-2-(5-bromo-4-cyano-2-fluorophenylamino)propanamide (59 mg, 0.137 mmol), 5-amino-3-methylisothiazole hydrochloride (35 mg, 0.232 mmol), K2CO3 (60 mg, 0.434 mmol), BINAP (25 mg, 0.040 mmol) and Pd(OAc)2 (15 mg, 0.066 mmol) in dioxane (2 mL) and DMSO (0.3 mL) was degassed with argon, then was stirred at 120 C for 18 h. The mixture was purified by HPLC to give (R)-3-(4-(1H-imidazol-1-yl)phenyl)-2-(4-cyano-2-fluoro-5-(3-methylisothiazol-5-ylamino)phenylamino)propanamide (9 mg).
