実験手順
A suspension of 3-fluoro-4-nitrophenol (2.0 g, 12.73 mmol), 10% Pd/C (0.4 g) and HCOOK (8.75 g, 101.85 mmol) in THF/H2O (70 mL/20 mL) was stirred at 50° C. for 5 hours, then cooled to rt, and filtered through CELITE®. The filtrate was diluted with water (30 mL) and extracted with THF (50 mL). The organic layer was dried over Na2SO4 and concentrated in vacuo. The residue was diluted with water (50 mL) and extracted with DCM (50 mL). The organic layer was dried over anhydrous Na2SO4 and concentrated in vacuo to give the title compound as a brown solid (1.17 g, 72.3%).
