실험 절차
22.0 g of 2,2-difluoro-7-triethylsilanyl-benzo[1,3]dioxole-5-carboxylic acid were dissolved using 200 ml of diethyl ether and 100 ml of methanol. Then, 35.0 ml of a 2M solution of trimethylsilyldiazomethane was added at 10° C.-20° C. Stirring was continued for 1 h at room temperature and the mixture then evaporated. Chromatography on silica gel using EA/HEP 1:10 yielded 17.0 g of the title compound, colorless oil. Rf (EA/HEP 1:20)=0.39
