4-(2-Fluoropyridin-3-yl)-1-methylpiperidin-2-one (0.07 g, 0.33 mmol), 4-(pyridin-2-ylamino)phenol (0.144 g, 0.77 mmol), cesium carbonate (0.274 g, 0.84 mmol), and 1-methyl-2-pyrrolidinone (1 mL) were combined in a sealed tube and heated at 100° C. for 18 h. The cooled mixture was diluted with EtOAc and washed with water; the aqueous layer was back-washed with EtOAc (1×). The combined organic extracts were dried (MgSO4), filtered, and concentrated in vacuo. ISCO purification with 20% to 80% EtOAc (10% MeOH)/Hexanes afforded 1-methyl-4-(2-(4-(pyridin-2-ylamino)phenoxy)pyridin-3-yl)piperidin-2-one (0.053 g, 42.1% yield) as a tan amorphous solid. MS (ESI, pos. ion) m/z: 375.0 (M+1). IC50 (uM) 0.005.
