Febuxostat intermediate and preparation method thereof |
| abstract |
The invention provides a febuxostat intermediate and a preparation method thereof. Febuxostat intermediate of the present invention is the compound shown in formula V: Formula V. The yield of Febuxostat obtained by the method for preparing Febuxostat intermediate of the present invention and the method for preparing Febuxostat by the Febuxostat intermediate is relatively high, which can be as high as more than 90%, and the resulting non- The purity of busostat is as high as 99%. In addition, the use of highly toxic cyanide can be avoided in the method for preparing Febuxostat intermediate of the present invention and the method for preparing Febuxostat through the Febuxostat intermediate, and the dehydrating agent used in the method is environmentally friendly and economical , suitable for industrialized mass production. |
