Reaction Conditions

Reaction Steps

5-chloro-2-methylbenzoic acid (4.0 g, 23 mmol) was added portionwise to cooled conc. H2SO4 (27 mL) at −10° C. After 10 minutes a nitrating mixture {prepared by mixing conc. HNO3 (3.3 g, 52.68 mmol) with conc. H2SO4 (4.4 mL)} was added dropwise at −10° C. The resulting reaction mass was stirred at −10° C. for 30 minutes. On completion, the reaction mixture was poured on ice cold water, the solid precipitate was filtered, washed with water and dried under vacuum giving the title compound (4.95 g, 99%).
