The reaction mixture was degassed by bubbling nitrogen through the solution for 10 min and the reaction mixture was heated to 78° C. After 4 h, the reaction mixture was diluted with EtOAc, washed with brine (1×), dried over MgSO4, filtered, and concentrated. Purification by flash column chromatography on silica gel (10% to 50% EtOAc in hexanes) gave 2-(3-fluorophenyl)-6-methylpyridin-3-amine.
