Методика

In a 50 mL round-bottomed flask was placed N-(4-(3-chloropyrazin-2-yloxy)-phenyl)pyridin-2-amine (0.2376 g, 0.7954 mmol) in DMSO. Piperidine-4-carbonitrile (0.4363 g, 3.977 mmol) was added and the temperature was brought to 80° C. to stir overnight. The reaction mixture was diluted with water (10 mL) and extracted with DCM (3×10 mL). The organic extract was washed with water (3×10 mL), satd sodium chloride solution (3×10 mL), dried with magnesium sulfate, filtered, and concentrated. The crude product was adsorbed onto a plug of silica gel and chromatographed through a Biotage™ pre-packed silica gel column (25M), eluting with a gradient of 1% to 5% methanol in DCM, to provide 1-(3-(4-(pyridin-2-ylamino)-phenoxy)pyrazin-2-yl)piperidine-4-carbonitrile. MS (ESI, pos. ion) m/z: 373.1 (M+1). IC50 (uM) 0.006048.
