500 mg of 4-(4-fluorophenyl)-4-hydroxy-1-phenylcyclohexanecarbonitrile were dissolved in 10 ml of dry dimethyl sulfoxide, treated with 190 mg of potassium hydroxide and stirred for 30 min at room temperature. Subsequently, 0.17 ml of bromomethylcyclopropane were slowly added dropwise. The reaction mixture was stirred for 24 h, treated with water and extracted with EA. The combined organic phases were dried over magnesium sulfate and the solvent was removed in vacuo. The crude product, a clear oil, was purified by chromatography on silica gel using HEP/EA (2:1). 510 mg of the title compound were obtained as a white solid.
