실험 절차

To a N2 purged solution of N-(4-(3-chloropyrazin-2-yloxy)phenyl)pyridin-2-amine (4.891 g, 16.37 mmol), potassium acetate (6.54 g, 66.6 mmol), dioxane:water (160 mL, 10:1), and tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1 (2H)-carboxylate (6.03 g, 19.50 mmol) was added A-Phos (1.5 g, 2.118 mmol). The vial was capped and placed in a preheated oil bath (120° C.) and stirred for 1.5 hours. The solution was allowed to cool to room temperature and poured into water. The aqueous solution was extracted with EtOAc (3×70 mL). The combined organic layers were concentrated in vacuo and adsorbed onto a plug of silica gel and chromatographed through a Redi-Sep® pre-packed silica gel column (120 g), eluting with 0% to 50% EtOAc in hexane, to provide tert-butyl 4-(3-(4-(pyridin-2-ylamino)phenoxy)pyrazin-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate as a yellow foam. MS (ESI, pos. ion) m/z: 446.1 (M+1). IC50 (uM) 0.01298.
