Reaktionsschritte

A mixture of N-t-butyloxycarbonyl-3,5-dinitro-4-methylaniline (7.8 g, from above) and trifluoroacetic acid (100 mL) was stirred at room temperature for 15 min. After evaporation of the solvent under reduced pressure, the residue was taken up in ethyl acetate (100 mL), washed with saturated sodium bicarbonate solution, half-saturated sodium chloride solution, and dried over magnesium sulfate. After evaporation of the solvent, the residue was purified by flash column chromatography on silica gel eluting with acetone:hexane (1:3) to give 4-methyl-3,5-dinitro-phenylamine (2.45 g).
