実験手順

A mixture of (R)-2-(3-bromo-4-cyanophenylamino)-3-cyclohexylpropanamide (222 mg, 0.634 mmol), 5-amino-3-methylisothiazole hydrochloride (126 mg, 0.840 mmol), BINAP (60 mg, 0.096 mmol), Pd(OAc)2 (45 mg, 0.200 mmol) and K2CO3 (360 mg, 2.60 mmol) in dioxane (4 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, washed with 1N HCl, then with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give (R)-2-(4-cyano-3-(3-methylisothiazol-5-ylamino)phenylamino)-3-cyclohexylpropanamide as a solid (241 mg).
