Procedure
To a solution of methylmagnesium bromide (40 mmol, 1 M in THF) was added a solution of 2,4-dimethyl-1-vinylcyclohex-3-enecarbaldehyde (34 mmol) dropwise at 10° C. The mixture was stirred at room temperature for 1 h and was then cooled to 5° C. A sat. solution of NH4Cl was added dropwise and the mixture was extracted with MTBE (3×50 ml). The combined org. phases were washed with water and brine, dried (MgSO4) and concentrated in vacuo. The residue was purified by chromatography to give (2,4-dimethyl-1-vinylcyclohex-3-enyl)ethanol (53% yield).
