Procedure

To a stirred solution of methyl 2-cyclohexyl-2-propenoate (2.0 g., 11.0 mmol) in 200 ml ethyl ether at -60° under argon was added diisobutylaluminum hydride (22 ml 1M solution in toluene). The solution was stirred for 0.5 hour, quenched with 3 ml isopropanol and warmed to room temperature. To this solution was added 25 ml water, and a white suspension formed. The mixture was filtered through celite, and the ether layer was washed twice with water, once with sodium chloride solution, dried over magnesium sulfate, filtered and concentrated to give a yellow liquid. This material was purified by flash chromatography (20% ethyl acetate/hexane) to give the alcohol as a clear liquid.
