Reaction Steps
To a suspension of 1,5-difluoro-2-methyl-3-nitrobenzene (21.0 g, 121.4 mmol) and 10% Pd/C (2.0 g) was added MeOH (200 mL) carefully and the flask was evacuated. The reaction mixture was flushed with hydrogen under balloon pressure and stirred at RT for 2 h. The reaction mixture was filtered through Celite bed and evaporated in vacuo to afford 3,5-difluoro-2-methylbenzenamine (18.0 g, 97%) as a dark yellow liquid.
