To a solution of benzaldehyde (3.05 mL, 30 mmol) in THF (30 mL) was added 2-methylallylmagnesium chloride (0.8 M in THF, 45 mL, 36 mmol, 1.2 equiv) under N2 at 0° C. (internal). The mixture was warmed to room temperature and was stirred for 1.5 h. The mixture was then poured into saturated aqueous NH4Cl solution (30 mL) and was extracted with EtOAc (2×30 mL). The combined organic layers were washed with brine (30 mL), then were dried (Na2SO4) and filtered. The solvent was removed by rotary evaporation and the residue was purified by Kugelrohr distillation to afford 4.33 g (89%) of 3-methyl-1-phenyl-1buten-1-ol as a colorless oil.
