実験手順
2.07 g of (2-phenoxy-5-thiazolyl)-methanol were added to a solution of (1R,3R) 2,2-dimethyl-3-(2-methyl-1-propenyl)-cyclopropane-1-carboxylic acid chloride prepared from 1.68 g of the corresponding acid in 30 ml of benzene and 1.7 ml of pyridine were slowly added thereto at 10° C. The mixture was stirred at 20° C. for 17 hours and was poured into dilute aqueous hydrochloric acid. The decanted aqueous phase was extractedwith ether and the combined organic phases were washed with water, dried and evaporated to dryness under reduced pressure. The residue was chromatographed over silica gel and was eluted with an 8-2 cyclohexane-ethyl acetate mixture to obtain 1.9 g of (2-phenoxy-5-thiazolyl)-methyl (1R,3R) 2,2-dimethyl-3-(2-methyl-1-propenyl)-cyclopropane-1-carboxylate.
