実験手順

A mixture of (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)-3-phenylpropanamide (128 mg, 0.424 mmol), 6-aminoquinoline (80 mg, 0.555 mmol), K2CO3 (100 mg, 0.724 mmol), BINAP (30 mg, 0.048 mmol) and Pd(OAc)2 (15 mg, 0.066 mmol) in dioxane (3 mL) was degassed with Ar, then was stirred at 110 C for 20 h. The mixture was concentrated in vacuo. The residue was purified by HPLC to give (R)-2-(5-cyano-6-(quinolin-6-ylamino)pyrazin-2-ylamino)-3-phenylpropanamide (21 mg).
