2-(tert-Butyldimethylsilanyloxy)-1-phenylethanone (8.0 g, 32 mmol), ethylene glycol (1.99 g, 32 mmol), and p-toluenesulfonic acid (50 mg) was suspended in benzene (50 ml). The mixture was stirred under reflux for 5 hours. The solvent was evaporated under reduced pressure. The residue was treated with water and ethyl acetate. The organic layer was dried over sodium sulfate and the solvent was evaporated under reduced pressure. The crude was purified by silica gel column chromatography (eluent; hexane/ethyl acetate=1/1) to give tert-butyldimethyl-(2-phenyl-[1,3]dioxolan-2-yl-methoxy)silane (5.5 g, 18.7 mmol, 58%) as a yellow oil.
