Reaction Steps
5.4 g (15.3 mmol) of methyltriphenylphosphate [sic] bromide are added to a suspension of 1.75 g (14.9 mmol) of potassium tert-butoxide in 20 ml of tetrahydrofuran. The reaction medium is stirred for 1 hour at 25° C. and then cooled to 0° C. A solution of 4.5 g (12.9 mmol) of ethyl4-(6-hexyl-3-oxoindan-5-yloxy)butyrate is added. The mixture is stirred for 16 hours at 25° C., poured into water and extracted with ether. The organic phase is dried (Na2SO4) and concentrated under reduced pressure (oil). Purification by flash chromatography (80/20 heptane/ethyl acetate) gives an orange oil (3.5 g; 79%).
