| titleOfInvention | Process for preparing 4-fluoro-2-nitrobenzoic acid |
| abstract | The invention is within the scope of drug synthesis. Hisnthe subject matter is a process for preparing an acidn4-fluoro-2-nitrobenzoic acid, which is importantnintermediate by the neuroleptic and antipsychotic routendrugs. Method of preparationnsaid acid is based on a two-stage processnprocess in which the first reaction isnhydrate of 4-fluoro-2-nitrobenzonitrile by treatmentn70% sulfuric acid at 100 ° C, and the othernthe reaction is the action of nitrous acid onnthe resulting 4-fluoro-2-nitrobenzamide also occurs atntemperature of 100 ° C. |
