FSO2CF2CF2COOCF2CF(CF3)OCF2CF(CF3)OCF2CF2CF3 (3.6 g) obtained in Example 2-5 was charged into a flask together with NaF powder (0.02 g) and heated at 140° C. for 10 hours in an oil bath with vigorous stirring. At the upper portion of the flask, a reflux condenser having the temperature maintained at 20° C. was installed. After cooling, a liquid sample (3.4 g) was recovered. As a result of the analysis by GC-MS, CF3CF2CF2OCF(CF3)CF2OCF(CF3)COF and the title compound were confirmed as the main products. The NMR yield of the title compound was 70.9%, and the yield of CF3CF2CF2OCF(CF3)CF2OCF(CF3)COF was 72.0%.
