実験手順

A mixture of (R)-3-(benzyloxy)-2-(3-bromo-4-cyanophenylamino)propanamide (66 mg, 0.176 mmol), 5-amino-3-methylisothiazole hydrochloride (35 mg, 0.232 mmol), BINAP (20 mg, 0.032 mmol), Pd(OAc)2 (15 mg, 0.066 mmol) and K2CO3 (100 mg, 0.724 mmol) in dioxane (2 mL) was degassed with Ar, then was stirred at 120 C for 18 h. Water and EtOAc were added. After being filtered, the organic phase was separated, dried over Na2SO4, concentrated in vacuo to give (R)-3-(benzyloxy)-2-(4-cyano-3-(3-methylisothiazol-5-ylamino)phenylamino)propanamide as a crude residue (73 mg).
