Nitric Acid → 5-Chloro-2-methyl-3-nitrobenzoic acid

Participants

Reaction Steps

5-chloro-2-methylbenzoic acid (4 g, 23.4 mmol) was added to cooled conc. H2SO4 (27 mL) at −10° C. in small portions and stirred for 10 minutes. Nitrating mixture {prepared by mixing Conc. HNO3 (3.3 g, 52.68 mmol) with conc.H2SO4 (4.4 mL)} was added drop wise at −10° C. The resulting mixture was stirred at −10° C. for 30 minutes. On completion, the reaction mixture was poured into ice cold water, the solid was collected by filtration, washed with water and dried under vacuum to give 5-chloro-2-methyl-3-nitrobenzoic acid (4.95 g, 99%).
