Reaction Conditions

Reaction Steps

Under an argon atmosphere, to a solution of ethyl diethoxyacetate (1.80 mL, 10.1 mmol) in THF (20 mL) was added slowly a THF solution of (103) prepared above at −78° C. After stirring at −78° C. for an hour, to this was added 20% aqueous solution of ammonium chloride (30 mL) and the product was extracted with ethyl acetate (×3). The organic layer was sequentially washed with water (×1) and saturated brine (×1), and dried over anhydrous sodium sulfate. After filtration, the mixture was concentrated under reduced pressure and the residue was purified by silica gel flash column chromatography (n-hexane/ethyl acetate=10/1) to give 3-[3-(tert-butyldimethylsilyloxy]phenyl]-1,1-diethoxypropan-2-one (104) as a colorless oily substance (1.90 g, 5.39 mmol, 53.9%).
