الإجراء التجريبي
Under an argon atmosphere, to a solution of 2-[4-(tert-butyldimethylsilyloxy)phenyl]acetic acid (9) (757 mg, 2.84 mmol) in CH2Cl2 (8 mL) was added DMF (2 drops) by a Pasteur pipette at room temperature. To this was added oxalyl dichloride (490 μL, 5.79 mmol) at 0° C. and the mixture was stirred for 30 minutes while elevating to room temperature. The mixture was concentrated under reduced pressure to give crude 2-[4-(tert-butyldimethylsilyloxy)phenyl]acetyl chloride (10) as a colorless oil, which was used in the following reaction without further purification.
