Procedure

To a solution of 10.01 g 3-[2-(tert-butyl-dimethyl-silanyloxy)-phenyl]-acrylic acid tert-butyl-dimethyl-silanyl ester in 25 ml of dichloromethane, three drops of dimethylformamide were added and 4.14 g oxalyl chloride was dropped in at 0° C. After stirring at 0° C. for 90 minutes and then at room temperature ovemight, the mixture was evaporated to dryness. The resulting brown solid (7.52 g) was not further purified.
