p-Benzyloxyphenyl acetonitrile (50 g) was added to dry tetrahydrofuran (250 ml) and cooled to −78° C. Lithium HMDS (20.8 g) in tetrahydrofuran (60 ml) was added slowly to the reaction mixture at −70° C. followed by dropwise addition of cyclohexanone (26.6 g. 0.27 mol) and maintaining the temperature at −60° C. for 2 h. The reaction temperature was allowed to rise to 0° C., charged with water (300 ml) and the organic layer was separated. The aqueous layer was then extracted with ethylacetate. The two organic layers were combined, washed with DM water and dried using Na2SO4. The solvent was evaporated under reduced pressure to give 50 g (70.0%) of 1-[cyano(p-benzyloxyphenyl)methyl]-cyclohexanol.
