Procedure

To a slurry of LiAlH4 (400 mg) in anhydrous ether (20 ml) is added dropwise at 0°, a solution of ethyl 4-[4-(4-trifluoromethylphenoxy)phenoxy]-3-methoxy-2-pentenoate (1.2 g) in ether (10 ml). After addition is complete, the reaction mixture is stirred for about 10 minutes. Excess hydride is decomposed with wet ether and water. After filtration, the filtrate is concentrated to give the alcohol, 4-[4-(4-trifluoromethylphenoxy)phenoxy]-3-methoxy-2-penten-1-ol.
