Reaction Conditions:

with N-Bromosuccinimide;acetic acid at 15;

Steps:

1 (1) Upper bromine reaction:
200 g of o-fluoronitrobenzene and 1000 mL of solvent acetic acid were added to the reaction vessel.The temperature was controlled at about 15 degrees, and 268 g of the bromine reagent N-bromosuccinimide was added in portions.After the addition is completed, stir for a while, GC tracking,Until the reaction is completed. After the reaction is completed, the ice water is hydrolyzed and filtered.Obtained an off-white solid 5-bromo-2-fluoronitrobenzene303 g,97% purity,The yield was 97.1%.
