実験手順

A mixture of (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)butanamide (80 mg, 0.334 mmol), 4-(pyridin-4-yl)aniline (56 mg, 0.329 mmol), K2CO3 (110 mg, 0.797 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 4 h. The mixture was concentrated in vacuo. The residue was purified by HPLC to give (R)-2-(5-cyano-6-(4-(pyridin-4-yl)phenylamino)pyrazin-2-ylamino)butanamide (57 mg).
