Ethyl 4-(4-amino-3-fluorophenoxy)-2-aminopyridin-3-yl-methyl-carbamate (7a) (320 mg, 1.0 mmol) was suspended in a solution of EtONa in EtOH (4 mL), obtained from dissolving sodium (480 mg, 21 mmol) in ethanol (9 mL). The suspension was heated under microwave irradiation for 1 hour (100° C., 100 W). The mixture was cooled at room temperature and the solvent was evaporated. The residue was dissolved in water and was acidified with AcOH to pH 4. The precipitate formed was recovered by filtration, to afford the title compound.
