Procedure

5,6-Difluoroindan-1-one (59.3 g, 0.353 mol) was dissolved in 1 L of ethanol and sodium borohydride (6.68 g, 0.176 mol) was added. The mixture was stirred for 48 hours and the ethanol was removed by evaporation under reduced pressure. The residue was partitioned between diethyl ether and water and the mixture was acidified with 1N hydrochloric acid. The mixture was dried over magnesium sulfate and filtered. The solvents were evaporated giving 5,6-difluoro-1-hydroxyindane (59.8 g) as an oil.
