| titleOfInvention | Method for producing oxadiazolinone compound |
| abstract | An object of the present invention is to provide a novel method capable of producing an oxadiazolinone compound (VI) from a diazonium salt in a good yield. A process for producing an oxadiazolinone compound (VI) comprising a diazonium salt (I), at least one selected from the group consisting of sulfites and hydrogen sulfites, and water at a pH of 5.5 to 7 After mixing at 45 to 100 ° C. in the range of 0.5, the resulting mixture is heat-treated at 45 to 100 ° C. and then subjected to contact treatment with acid (A), obtained in step (A). The step (B) of reacting the phenylhydrazine compound (II) with the halogenated alkyl carbonate (III) or dialkyl dicarbonate (IV), and the phenylhydrazine-β-carboxylate compound obtained in the step (B) ( V) and phosgene are reacted, and then the step (C) is brought into contact with a basic compound. [Selection figure] None |
