Procedure

A mixture of (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)butanamide (80 mg, 0.334 mmol), 6-amino-3,4-dihydroquinolin-2(1H)-one (60 mg, 0.370 mmol), K2CO3 (100 mg, 0.724 mmol), BINAP (25 mg, 0.040 mmol) and Pd(OAc)2 (10 mg, 0.044 mmol) in dioxane (2 mL) was degassed with Ar, then was stirred at 110 C for 4 h. The mixture was concentrated in vacuo. The residue was purified by HPLC to give (R)-2-(5-cyano-6-(2-oxo-1,2,3,4-tetrahydroquinolin-6-ylamino)pyrazin-2-ylamino)butanamide (72 mg).
