Reaction Steps

Under an argon atmosphere, 1-diazo-3-(4-methoxyphenyl)propan-2-one (62) (477 mg, 2.51 mmol) was dissolved in anhydrous ethanol (5 mL) and cooled to 0° C. To this was added tert-butyl hydochloride (285 μL, 2.52 mmol) and stirred for an hour at the same temperature. After concentrating under reduced pressure, the residue was purified by silica gel flash column chromatography (n-hexane/ethyl acetate=10/1) to give 1,1-diethoxy-3-(4-methoxyphenyl)propan-2-one (63) as a colorless oily substance (357 mg, 1.41 mmol, 56.4%).
