実験手順

tert-Butyl (2R,3R)-1-(6-chloro-5-cyanopyrazin-2-yl)-2-methylpiperidin-3-ylcarbamate (311) (390 mg, 1.1 mmol), 4-(1-cyclopentylpiperidin-4-yl)aniline HCl salt (304) (406 mg, 1.7 mmol), fine-powder Cs2CO3 (1.1 g, 3.3 mmol), BINAP (207 mg, 0.33 mmol), and Pd(OAc)2 (75 mg, 0.33 mmol) were combined and suspended in dioxane (30 mL) and water (1 mL). The mixture was sparged with nitrogen stream for 10 minutes, and then stirred under nitrogen atmosphere in 115° C. oil bath for 5 hours. The mixture was cooled to RT, diluted with EtOAc (100 mL), stirred, filtered and concentrated under reduced pressure. The resulting residue was subjected to silica flash column chromatography (MeOH/DCM) to give tert-butyl (2R,3R)-1-(5-cyano-6-(4-(1-cyclopentylpiperidin-4-yl)phenylamino)pyrazin-2-yl)-2-methylpiperidin-3-ylcarbamate (312) (430 mg, 0.74 mmol, 68% yield).
