実験手順

A mixture of tert-butyl (1S,2R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)cyclohexylcarbamate (100 mg, 0.284 mmol), 3-(pyrimidin-2-yl)aniline (100 mg, 0.584 mmol), K2CO3 (118 mg, 0.855 mmol), BINAP (30 mg, 0.048 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 20 h. Water and EtOAc were added. Organic phase was separated, dried over Na2SO4, concentrated in vacuo to give a crude tert-butyl (1S,2R)-2-(5-cyano-6-(3-(pyrimidin-2-yl)phenylamino)pyrazin-2-ylamino)cyclohexylcarbamate.
