Reaction Steps
Acetonitrile (4.1 g, 0.10 mole), ethyl pentafluoropropionate (9.61 g, 0.05 mole) and a solution of n-butyllithium in n-hexane (70 ml, 0.11 mole) were reacted according to the same procedure as described in Example 1 to give 7.28 g (77.8%) of the title compound. When the resulting compound was dissolved in CDCl3 and its NMR was measured, the ratio of the keto form/the enol form was found to be 26/74, m.p. 47°-54° C. (deliquescence), b.p. 69°-71° C./18 mmHg.
