1-Fluoro-5-methyl-2,4-dinitrobenzene → 4-Fluoro-6-methylbenzene-1,3-diamine

Participants

Reaction Steps

2 g (0.01 ml) of 5-fluoro-2,4-dinitrotoluene from Step 1 are hydrated with catalytic amounts of palladium/carbon (10% Pd) in 50 ml absolute ethanol. After the catalyst is removed by filtration, the solvent is distilled off completely and the obtained product is recrystallized from toluene. 0.7 g (50 % of theory) of 5-fluoro-2,4-diaminotoluene is obtained which melts at 112° Celsius accompanied by decomposition.
