実験手順

Using the orocedure of Step F of Example 9, the acid of Step D of Example 1 and (R)α-ethynyl-3-phenoxy-benzyl alcohol were reacted to obtain (R)α-ethynyl-3-phenoxy-benzyl (1R,cis) 2,2-dimethyl-3[(Z) 3-oxo-3(2,2,2-trifluoroethoxy)-1-propenyl]-cyclopropane-carboxylate with a specific rotation of [α]D20 =+42°±1.5° (c=1% in CHCl3).
