YieldReaction ConditionsOperation in experiment
86.5% To a solution of <strong>[37901-90-9]3-amino-4-methyl-2-nitrobenzoic acid</strong> (48.5 g, 0.25 mol, 1.0 eq. ) in HBr (500 niL) at 0 C was added NaN02(30.7 g, 0.44mol, 1.8 eq.) in water (100 niL) dropwise. After 15 min, Cu powder (2.91 g, 0.045 mol, 0.18 eq. ) was added in portions. After 30 min, the mixture was heated at 60 C for 1 h, then cooled and added ice-water until a yellow precipitate formed. The precipitate was filtered, washed with water and dried in vacuo to afford 3-bromo-4-methyl-2-nitrobenzoic acid (56.7 g, 86.5% yield).
