To a stirred solution of 1.95 g (0.011 mol) 2-fluoro-4-(1-hydroxy-1-methyl-ethyl)-benzonitrile in 30 mL anhydrous THF at 0° C. was added dropwise 34 mL (0.034 mol) 1.0M LiAlH4. The mixture was warmed to room temperature then heated to reflux for 30 minutes. The mixture was then cooled to 0° C. and quenched with 20 mL MeOH added dropwise. Next, it was diluted with 700 mL CHCl3 and washed with 100 mL water. The resulting suspension was filtered through Celite and the organic layer dried over MgSO4 and concentrated to give 1.6 g of an amber oil.
