Reaction Conditions

Reaction Steps

6.5 g of 5-fluoro-1-indanone are dissolved in 50 ml of dry dimethylacetamide and, after addition of 36.5 g of anhydrous ground potassium carbonate and 12.9 g of 2,2,3,3,3-pentafluoropropanol, stirred at 95-100° C. for 10 h. The solvent is then removed by distillation in vacuo; 300 ml of water are added to the residue, and the aqueous phase is extracted with ethyl acetate several times. The organic phase is washed with water, dried over sodium sulfate and concentrated in vacuo. Purification on silica gel affords 5-(2,2,3,3,3-pentafluoropropoxy)-1-indanone as a brown oil which crystallizes after some time; melting point 52-54° C.
