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

참여 물질

반응 단계

A stirred solution of 5-chloro-2-methylbenzoic acid (1 mmol) in conc. H2SO4 (2 mL) was cooled to −10° C. and nitrating mixture (0.4 mL of conc. H2SO4+0.1 mL of conc. HNO3) was added to it in dropwise manner. The reaction mixture was stirred at the same temperature for 20 min then warmed to room temperature. The solid precipitate was filtered and dried to obtain 5-chloro-2-methyl-3-nitrobenzoic acid which was used in next step without further purification (yield 60-70%).
