Versuchsvorschrift
In an atmosphere of nitrogen, tetrakistriphenylphosphine palladium was added to a mixture of 2-bromo-1,3-dimethylbenzene, 2-fluoro-5-formylphenyl boronic acid, a 1 M sodium carbonate aqueous solution, ethanol and toluene, followed by stirring at 80° C. for 8 hours to obtain 6-fluoro-2′,6′-dimethylbiphenyl-3-carbaldehyde. Under cooling on an ice-methanol bath, sodium borohydride was added in small portions to an ethanol solution of the resulting 6-fluoro-2′,6′-dimethylbiphenyl-3-carbaldehyde, and the reaction mixture was stirred at the same temperature for 1 hour to obtain (6-fluoro-2′,6′-dimethylbiphenyl-3-yl)methanol.
