実験手順

2 ml of 2,2,2-trifluoroethanol were added at 20° C. to a solution of 2.14 g of the product of Step D in 8 ml of methylene chloride and the mixture was stirred for 90 minutes and was poured into aqueous monosodium phosphate solution. The decanted organic phase was washed with water, dried and evaporated to dryness under reduced pressure. The residue was chromatographed over silica gel and was eluted with a 1--1 cyclohexane-ethyl acetate mixture to obtain 2.33 g of (S)α-cyano-3-phenoxy-4-fluoro-benzyl (1R,cis,Z) 2,2-dimethyl-3-[3-oxo-3-(2,2,2-trifluoroethoxy)-1-propenyl]-cyclopropane-carboxylate melting at 56° C. and having a specific rotation of [αD20 =+42°±1° (c=1% in CHCl3).
