- Preparation method of 4-cyano-2-fluorobenzyl alcohol
-
The invention discloses a preparation method of 4-cyano-2-fluorobenzyl alcohol, and belongs to the technical field of medical intermediates. 3, 4-difluorobenzonitrile is adopted as a raw material and reacts with potassium bromide in the presence of a phase transfer catalyst, or 3-fluoro-4-bromobenzaldehyde and hydroxylamine are subjected to a dehydration reaction to obtain 3-fluoro-4-bromobenzonitrile, and then the 3-fluoro-4-bromobenzonitrile is subjected to Grignard reagent exchange and reacts with paraformaldehyde to obtain the 4-cyano-2-fluorobenzyl alcohol. The method is safe and stable, the obtained product is easy to purify, and the method has potential industrial amplification prospects.
