N-(4,5-Difluoro-2-nitrophenyl)acetamide → 4,5-Difluoro-2-nitroaniline
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | N-(4,5-Difluoro-2-nitrophenyl)acetamide | HCID 540127 | — |
| Solvent | Hydrochloric Acid | HCID 313 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 4,5-Difluoro-2-nitroaniline | HCID 157151 | 94.3% |
Reaction Steps
A solution of N-(4,5-difluoro-2-nitrophenyl)acetamide (70 g) in concentrated hydrochloric acid (110 ml) and ethanol (440 ml) was refluxed for 2 hours. The reaction mixture was poured into ice water (1.5 liter) and the resulting precipitate was collected by filtration and washed with chilled water sufficiently to give the title compound (53.2 g) as yellow prisms, mp 109°-109.5° C.
