Abstract

Oppfinnelsen angår en fremgangsmåte for fremstilling av 4-cyano-4'-hydroksybifenyl, idet nevnte fremgangsmåte omfatter beskyttelse av hydroksygruppen i 4-fenyl-fenol, acylering av den beskyttede 4-fenyl-fenol-gruppen, omdannelse av det resulterende keton til en syre, amidering av den således oppnådde syren, dehydratisering av det resulterende amid og avbeskyttelse av hydroksygruppen.
