Versuchsvorschrift

To a 100 mL round-bottomed flask was added 2-(4-(pyridin-2-ylamino)phenoxy)nicotinic acid (0.333 g, 1.08 mmol), cyclopropylmethanamine hydrochloride (0.116 g, 1.08 mmol), and TEA (0.4500 mL, 3.25 mmol) in DMF to stir for 5 min. EDC (0.2314 g, 1.19 mmol) and HOBT (0.1870 g, 1.19 mmol) was then added and allowed 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 (1×10 mL), saturated sodium chloride (1×10 mL), saturated sodium bicarbonate (1×10 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 N-(cyclopropylmethyl)-2-(4-(pyridin-2-ylamino)phenoxy)nicotinamide. MS (ESI, pos. ion) m/z: 361.1 (M+1). IC50 (uM) 0.831.
