Procedure

To a mixture of 2,4-dimethylaniline (10 mmol) in 5 mL of conc. H2SO4, fuming HNO3 (90%; 0.6 mL) was added dropwise at 0° C. The resulting mixture was stirred for 12 h at RT and then slowly poured into ice. The solid was collected by filtration and dried to yield 2,4-dimethyl-5-nitroaniline as a yellow solid.
