Reaction Conditions

Reaction Steps

20.2 g (0.297 mol) of imidazole are added to a solution of 9.5 g (0.175 mol) of sodium methylate in 49 ml of methyl alcohol. A slution of 44.3 g (0.135 mol) of 1-(4-biphenylyl)-2-chloro-1-(4-fluorophenyl)-ethanol in 103 mol of dimethylformamide is then added dropwise, and the reaction mixture is heated to 60° C. for 90 minutes. It is concentrated by distilling off the solvent in vacuo, and the residue is stirred with water. The crystals which remain are washed with acetonitrile and recrystallised from ethyl alcohol. 13.5 g (28% of theory) of 1-(4-biphenylyl)-1-(4-fluorophenyl)-2-(imidazol-1-yl)-ethanol of melting point 220° C. are obtained.
