実験手順
A mixture of 2-[2-(hydroxymethyl)cyclopropyl]phenyl 4-(trifluoromethyl)-benzenesulfonate (0.70 g, 1.9 mmol), carbon tetrachloride (2.5 mL), acetonitrile (2.5 mL), water (3.8 mL), sodium periodate (1.8 g, 8.4 mmol) and ruthenium choride hydrate (75 mg, 0.4 mmol) is stirred at room temperature overnight. The reaction is partitioned between ethyl acetate and dilute HCl. The organic layer is filtered through anhydrous sodium sulfate, evaporated and purified on silica gel in ethyl acetate-methylene chloride-acetic acid mixtures. The product, 2-[2-({[4-(trifluoromethyl)phenyl]sulfonyl}oxy)phenyl]cyclopropanecarboxylic acid, is obtained as a mixture of isomers. A yield of 95% is obtained.
