الإجراء التجريبي

Under an argon atmosphere, to a mixture of 2-[4-(tert-butyldimethylsilyloxy)phenyl]acetic acid (9) (1.80 g, 6.76 mmol) in CH2Cl2 (15 mL) was added DMF (4 drops) by a Pasteur pipette at room temperature. To this was added oxalyl dichloride (1.20 mL, 14.2 mmol) at 0° C. and the mixture was stirred for an hour 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.
