실험 절차

Using the procedure of Step B of Example 43, (1R,cis,E) 2,2-dimethyl-3-[2-fluoro-3-oxo-3-(2,2,2-trifluoroethoxy)-1-propenyl]-cyclopropane carboxylic acid and (S)α-cyano-3-phenoxy-4-fluoro-benzyl alcohol were reacted to obtain (S)α-cyano-3-phenoxy-4-fluoro-benzyl (1R,cis,E) 2,2-dimethyl-3-[2-fluoro-3-oxo-3-(2,2,2-trifluoroethoxy)-1-propenyl]-cyclopropanecarboxylate melting at 85° C. and having a specific rotation of [α]D20 =+43°±2.5° (c=0.65% in chloroform).
