To a stirred and refluxing mixture of 23.4 parts of (4-chlorophenyl) (2-fluorophenyl)methanone in 280 parts of 2-propanol are added portionwise 3.7 parts of sodium borohydride. Upon completion, stirring is continued for 2 hours at reflux temperature (±80° C.). The reaction mixture is cooled and decomposed by the addition of water. The 2-propanol is evaporated and the residual product is extracted with trichloromethane. The extract is dried, filtered and evaporated, yielding 4-chloro-α-(2-fluorophenyl)benzenemethanol as a residue.
