Versuchsvorschrift

10% Pd—C 4.0 g was added to 3-fluoro-4-morpholinyl nitrobenzene (40 g, 177 mmol), ammonium formate (50 g, 793 mmol) in 200 mL of ethyl acetate and stirred at 45˜50° C. for 8 h until the completion of the reaction. The mixture was then filtrated and separated by water. The organic layer was washed with brine and dried over anhydrous magnesium sulfate, filtered, and the solvent was evaporated to provide 33 g of solid in 95% yield.
