Reaktionsschritte

5-Bromo-2,4-dimethylbenzoic acid (12 g, 52.17 mmol) was added to cooled conc. H2SO4 (48 mL) at −10° C. lot wise. After 10 minutes nitrating mixture {prepared as mixing Conc. HNO3 (6 mL) with conc.H2SO4 (24 mL)} was added drop wise at −10° C. Resulting reaction mass was stirred at −10° C. for 30 minutes. On completion, reaction mixture was poured on ice cold water, solid precipitated was filtered, washed with water and dried under vacuum giving desired compound (13 g, 91%).
