Reaction Steps

To 4-amino-2-fluorophenol (0.983 g, 7.73 mmol) was added NMP (3 mL) and 2-fluoropyridine (0.670 mL, 7.78 mmol). The reaction mixture was heated to 120° C. for 12.5 h and the temperature was increased to 150° C. After 9 h, the reaction mixture was diluted with EtOAc and the organic phase was washed with saturated NaHCO3 (1×), brine (1×), dried over MgSO4, filtered, and concentrated. Purification by flash column chromatography on silica gel (10% to 70% EtOAc in hexanes) gave 2-fluoro-4-(pyridin-2-ylamino)phenol as a pale yellow oil. MS (ESI, pos. ion) m/z: 205.2 (M+1).
