Procedure
A solution of methylmagnesium bromide in ether (4 ml) was added to a solution of 3-isobutylbenzaldehyde (1.0 g) in tetrahydrofuran (10 ml) at 0° C. After stirred at 0° C. for 30 minutes, the mixture was partitioned between ether and 1N hydrochloric acid. The organic layer was separated, washed with water and brine, and dried over magnesium sulfate. After evaporation of the solvent, the residue was chromatographed on silica gel (30 g) eluting with a mixture of ethyl acetate and hexane (1:10) to give 1-(3-isobutylphenyl)ethanol (1.12 g) as an oil.
