実験手順

A mixture of (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)-3-(thiophen-2-yl)propanamide (92 mg, 0.299 mmol), 6-aminoquinoline (60 mg, 0.416 mmol), K2CO3 (80 mg, 0.579 mmol), BINAP (25 mg, 0.040 mmol) and Pd(OAc)2 (15 mg, 0.066 mmol) in dioxane (2 mL) was degassed with Ar, then was stirred at 110 C for 6 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-(thiophen-2-yl)propanamide (40 mg).
