Reaction Steps
A mixture of 3,5-dimethoxybenzyl alcohol (4.0 g), tert-butyl-diphenylsilyl chloride (6.54 g) and imidazole (3.28 g) in DMF (60 mL) was stirred at room temperature for 24 h. DMF was evaporated and the residue was purified by column chromatography (silica gel; eluent: hexane to hexane/EtOAc 20% ) to yield 8.5 g of 3,5-dimethoxybenzyl tert-butyldiphenylsilyl ether. ESMS: m/z 407 (MH+).
