Reaction Steps

Rhodium (II) acetate dimer (approximately 10mg) was suspended in a solution of the indanol (Example 3, step B, 0.5g) in dry toluene (10 cm3). A solution of ethyl diazoacetate (0.18g) in a small volume of dry toluene was slowly added dropwise to the reaction mixture. Effervescence was observed, the solid dissolved and the solution turned a blue green colour. The mixture was allowed to stand at room temperature overnight then poured into water. The aqueous mixture was extracted with diethyl ether, washed with brine, dried over anhydrous sodium sulphate, filtered and concentrated under reduced pressure. Preparative thin layer chromatography (silica/hexane-ether, 7:3) gave compound 3, ethyl (RS)-6-(2-chloro-6-fluoro-4-trifluoromethylphenoxy)indan-1-yloxyacetate, as a colourless oil (0.17g,27%).
