실험 절차
10.09 ml (60 mmol) trifluorometansulfonic anhydrid dissolved in CH2Cl2 was added dropwise to a mixture of 4.05 ml (50 mmol) methylglycolate and 4.04 ml (50 mmol) pyridin in CH2Cl2 (totally 62.5 ml) at 0° C. during 25 minutes, and thereafter stirred at 0° C. for 1 H. After washing with 0.3M KHSO4 and saturated NA2CO3, drying (Na2SO4) and filtration, evaporation of the solvent in vacuo gave 9.94 g (90%) of the title compound.
