Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Nitric Acid | HCID 944 | — |
| Reactant | Carbonic acid, 2-bromo-4-fluorophenyl methyl ester | HCID 13268177 | — |
| Solvent | Sulfuric Acid | HCID 1118 | — |

Reaction Steps
Then, 110 g (0.44 mol) of methyl 2-bromo-4-fluorophenoxyformate was dissolved in 250 ml of sulfuric acid, to which a mixed acid of 30 g of fuming nitric acid and 30 ml of sulfuric acid was added dropwise at 5° C. or lower, and the mixture was stirred for 2 hours. The reaction mixture was poured onto ice, and the precipitated crystals were collected by filtration, washed with water, and dried, which afforded 126 g (0.43 mol) of methyl 2-bromo-4-fluoro-5-nitrophenoxyformate.
