実験手順
To 2-fluoro-3-nitro-benzoic acid (70, 6.77 g, 36.6 mmol) in 150 mL of methanol, Palladium on carbon (5:95 Palladium:Carbon, 0.338 g, 0.159 mmol) is added under a balloon of hydrogen. The reaction is stirred at room temperature for 40 hours, then a new balloon of hydrogen is attached, and the reaction continued for 5 hours. The reaction is filtered and the filtrate is concentrated under vacuum to provide the desired compound (71, 5.62 g). MS (ESI) [M−H+]−=154.1.
