Product 1

HCID 86740323alpha-methyl-3-phenoxyl-benzyl (1R,cis) 2,2-dimethyl-3-[3-oxo-3-(2,2,2-trichloroethoxy)-1-propynyl]-cyclopropane-carboxylate

Procedure

Using the procedure of Step D of Example 9, 6 g of (1R,cis) 2,2-dimethyl-3-[3-oxo-3-(2,2,2-trichloroethoxy)-1-propynyl]-cyclopropane-carboxylic acid and 4.1 g of 1-(R) (3-phenoxyl-phenyl)- ethanol were reacted to obtain after chromatography and elution with an 8-2 mixture of cyclohexaneethyl acetate 4.38 g of (R)α-methoxy-3-phenoxy-benzyl (1R, cis) 2,2-dimthyl-3-[3-oxo-3-(2,2,2-trichloroethoxy)-1-propynyl]-cyclopropane-carboxylate.
