Procedure

3.80 g (86.6 mmol) sodium hydride (55%, suspension in mineral oil) were added batchwise to 20.0 g (86.6 mmol) 4-bromo-2-methyl-6-nitroaniline in 250 mL DMF with slight cooling and the mixture was stirred for 30 min. Then 5.40 mL (86.6 mmol) methyl iodide were slowly added dropwise, the cooling was stopped and the mixture was stirred overnight at RT. Then water was slowly added while the mixture was cooled and it was extracted several times with EtOAc. The organic phases were combined, dried on sodium sulphate, filtered and evaporated down i.vac. The residue was recrystallised from DIPE, cooled and the precipitate was suction filtered and dried.
