Title:
PREPARATION METHOD FOR CARBON-LOADED IRON-BASED CATALYST AND USE THEREOF IN SYNTHESIS OF INTERMEDIATES OF ANTI-CANCER INHIBITORS
Document Type and Number:
WIPO Patent Application WO/2023/098592
Kind Code:
A1
Abstract:
The present invention provides a carbon-loaded iron-based catalyst, and a preparation method thereof and a use. The preparation method comprises dissolving ferric chloride in water, adding activated carbon, adding sodium hydroxide at 60-100°C,repeating the reaction, then drying at 60-400°C for 12-24 h. The carbon-loaded iron-based catalyst of the present invention can be used in the synthesis of key intermediates of anti-cancer drugs such as Osimertinib, Gefitinib, Afatinib, Imatinib, AMMG 510, Dacomitinib, Ceritinib, Lapatinib, and Apatinib. In the synthesis method, the key intermediate is synthesized at a relatively high yield under temperate conditions, the above mentioned carbon-loaded iron-based catalyst being used as a catalyst, hydrazine hydrate being the hydrogen source, and the solvents being solvents such as methanol, ethanol, or isopropanol. The carbon-loaded iron-based catalyst disclosed by the present invention can be repeatedly used around ten times after being washed with a solvent, dried and activated. This catalyst preparation method has a simple process, and is green, efficient, and low in cost, and it has good functional group compatibility and simple post-processing, having potential value for industrial production.
