A solution of N-(4-(2-aminopyridin-4-yloxy)-2-fluorophenyl)pivalamide (70 mg, 0.23 mmol) in 3 mL of MeOH was added 2 mL of 6 N HCl. The mixture was then heated at reflux for 48 h. After cooling down, the solvent was removed under reduced pressure and the residue was purified by solid extraction (Waters Oasis® MCX extraction cartridge) to give 4-(4-amino-3-fluorophenoxy)pyridin-2-amine (27 mg, 54% yield). MS(ESI+): m/z 220.21 (M+H)+.
