Reaktionsschritte

To a solution of (4-bromobenzyloxy)(tert-butyl)dimethylsilane (3.080 g) in THF (20 mL) were added Mg (0.288 g) and I2 (cat) at room temperature under an Ar atmosphere. The mixture was heated at 50° C. for 1 hour, and then cooled to room temperature. To the mixture was added 1,2-epoxypropane (0.77 mL) at room temperature under an Ar atmosphere, and the mixture was stirred at room temperature for 14.5 hours, and then heated at 50° C. for 1 hour, and then cooled to room temperature. To the mixture was added saturated aqueous NH4Cl, and the mixture was extracted with AcOEt. The organic layer was washed with saturated aqueous NaCl, dried over anhydrous Na2SO4, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (n-hexane/AcOEt=2/1) to afford 1-[4-({[tert-butyl(dimethyl)silyl]oxy}methyl)phenyl]propan-2-ol (1.485 g) as a colorless oil.
