This compound was prepared from 3-(2-chloro-2-trifluoromethylvinyl)-2,2-dimethylcyclopropanecarboxylic acid and α-fluoro-3-phenoxybenzyl bromide following the procedure described in Example 2 Method B. The product, a colourless oil, was characterised by pmr spectroscopy. Chemical shift δ ppm (solvent CDCl3): 1.26(6H, m, C(CH3)2); 1.72-2.44(2H, m, cyclopropyl protons); 5.80 and 6.18(1H, 2xd, vinyl proton); 7.20(1H, d, J=56Hz, CHF) and about 7.13(9H, m, aromatic protons).
