Step 2: Pd/C (10%) was added to a solution of N-methyl-2,4-dinitroaniline (12.14 g, 60.9 mmol) in acetonitrile (35 mL) and triethylamine (36.4 mL). The reaction mixture was cooled to -15 °C, followed by dropwise addition of formic acid (11.1 mL) to a solution of acetonitrile (35 mL). The reaction mixture was refluxed for 3 hours and then thermally filtered. The filtrate was concentrated under reduced pressure to afford N1-methyl-4-nitrobenzene-1,2-diamine (Product 2) as a red liquid in >95% yield.
