Reaction Steps
To a solution of 4-hydroxy-1-phenyl-butan-1-one (3.29 g, 20 mmol) in DMF (20 mL) was added tert-butylchlorodimethyl-silane (4.5 g, 30 mmol) and imidazole (4.1 g, 60 mmol). After stirring at room temperature for 14 hours, the reaction mixture was diluted with diethyl ether (150 mL) and washed with 1M HCl (2×70 mL), water (2×70 mL) and brine (100 mL). The combined organics were dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by flash column chromatography (6% ethyl acetate in hexanes) to provide the product (5 g, 90%) as a colorless oil.
