Reaction Steps

A mixture of (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)-4-methylpentanamide (80 mg, 0.299 mmol), 4-amino-N-methyl-indole (62 mg, 0.424 mmol), K2CO3 (65 mg, 0.471 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 100 C for 20 h. Water and EtOAc were added. Organic phase was separated, dried over Na2SO4, concentrated in vacuo to give (R)-2-(5-cyano-6-(1-methyl-1H-indol-4-ylamino)pyrazin-2-ylamino)-4-methylpentanamide as a crude residue (151 mg).
