To a solution of 2-fluoro-6-nitroaniline (2 g, 12.8 mmol) in MeOH (15 mL) palladium 10 wt % on carbon (180 mg, 75 μmol) was added under N2. After flushing the flask with N2 for 2 min, the solution was stirred under a H2 balloon. After 6 h, the mixture was filtered through a celite pad rinsed with MeOH, and concentrated under reduced pressure. The residue was purified by column chromatography on a silica gel column using EtOAc:DCM (1:1) as eluent to give 3-fluorobenzene-1,2-diamine: LC-MS (ESI) m/z 127.2 [M+H]+.
