To a slurry of LAH (65 mg, 1.7 mmol) in ether (4 ml) at 0 ƒC under Ar, the diene ester [1] (487 mg, 1.7 mmol) in ether (5 ml) was added dropwise. After addition was complete, the reaction was quenched with sat aq Na₂SO₄. The solution was filtered and the solids were washed with ether (5 x 10 ml). The combined organic layers were dried over Na₂SO₄ and concentrated to give, after flash chromatography (1 : 1 pet ether : ether) the title alcohol as a colorless oil, 354 mg, in 97 percent yield.
