| titleOfInvention | The preparation method of a kind of metconazole and intermediate thereof |
| abstract | The present invention relates to a kind of novel method preparing metconazole, the method is that initial feed obtains the intermediate 5-(4-chlorobenzyl)-2 of metconazole through series reaction with 4-chloro-benzaldehyde and 2-methoxycarbonyl cyclopentanone and formula (1) compound, 2-cyclopentanone dimethyl, i.e. formula (5) compound, reactant is obtained again by formula (5) compound and trimethylammonium bromination thioether reactant, reactant reacts obtained metconazole again with 1,2,4-1H-triazole.The technique of the method is simple, and raw material is easy to get, and cost is lower, and the three wastes of generation are few, and the content of target product metconazole and yield are all higher, and content can reach more than 95%, and total recovery can reach more than 65%, is applicable to suitability for industrialized production. |
