With palladium diacetate; potassium carbonate; 2,2'-bis-(diphenylphosphino)-1,1'-binaphthyl; In 1,4-dioxane; at 110.0℃; for 20.0h;Inert atmosphere;
Example 18 5-((1R,2R)-2-amino-3,3-difluorocyclohexylamino)-3-(4-(isoxazol-5-yl)phenylamino)pyrazine-2-carboxamide A mixture of 5-((1R,2R)-2-amino-3,3-difluorocyclohexylamino)-3-chloropyrazine-2-carbonitrile (74 mg, 0.257 mmol), <strong>[832740-73-5]4-(isoxazol-5-yl)aniline</strong> (60 mg, 0.375 mmol), K2CO3 (80 mg, 0.579 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 20 h. The mixture was concentrated in vacuo. The residue was purified by HPLC to give 5-((1R,2R)-2-amino-3,3-difluorocyclohexylamino)-3-(4-(isoxazol-5-yl)phenylamino)pyrazine-2-carbonitrile (4 mg).
