Reaction Steps

To a solution of (E)-3-methyl-5-(3,5-dichloro-phenyl)-pent-2-en-4-ynoic acid ethyl ester (130 mg, 0.46 mmol) in THF (0.5 mL) was added dropwise diisobutylaluminium hydride (1.0 M solution in toluene, 2.1 mL, 2.1 mmol) at −20° C. The reaction mixture was stirred for 2 hours at −20° C., whereafter saturated ammonium chloride was added. The mixture was treated with ethyl acetate and decalite and filtered. The filtrate was evaporated to give crude (E)-3-methyl-5-(3,5-dichloro-phenyl)-pent-2-en-4-yn-1-ol in 113 mg yield.
