A mixture of 4.5 g of 3-chloromethyl-5-phenoxy-(1,2,4)-thiadiazole, 3.7 g of (1R,3R) 2,2-dimethyl-3-(2-methyl-1-propenyl)-cyclopropane-1-carboxylic acid, 50 ml of methyl ethyl ketone, 3.2 g of potassium carbonate and 0.1 gof 1,4,7,10,13,16-hexaoxacyclooctadecane was refluxed for 18 hours and was cooled and filtered. The filtrate was evaporated to dryness under reduced pressure and the residue was chromatographed over silica gel. Elution withbenzene yielded 2.2 g of [5-phenoxy-(1,2,4)-thiadiazol-3-yl]-methyl (1R,3R)2,2-dimethyl-3-(2-methyl-1-propenyl)-cyclopropane-1-carboxylate.
