Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methylamine | HCID 6329 | — |
| Reactant | 2,4-Difluoronitrobenzene | HCID 67967 | — |
| Solvent | Water | HCID 962 | — |
| Product | 5-fluoro-N-methyl-2-nitroaniline | HCID 22905774 | 99% |
Reaction Steps
2,4-Difluoro-1-nitrobenzene (25.0 g, 157 mmol) was stirred and thereto was added dropwise 40% aqueous methylamine solution (38.4 g) at 0° C. over not less than 15 min. After the completion of the dropwise addition, the mixture was continuously stirred at the same temperature for 1.5 hr. Water (500 mL) was added to the reaction mixture, and the resulting solid was collected by filtration to give the title compound (26.4 g, 99%) as yellow crystals.
