Use | 6-chloro-4-iodoindazole is a heterocyclic derivative and can be used as a pharmaceutical intermediate. |
preparation | O-fluoroaniline is used as raw material, after NCS chlorination, then NBS iodination, 2-fluoro-4-chloro-6-iodobenzaldehyde was prepared by the reaction of re-diazotization with formaldehyde oxime, which was cyclized with 80% hydrazine hydrate to give 4-iodo-6-chloroindazole. The synthetic route is shown below. |
