実験手順
To the clear solution of 4,7-Dimethoxyindane (22.5 gm, 0.126 mole) in Methylene chloride (400 ml), added Boron tribromide (12.27 ml, 0.13 mole) at 0° C. After 2 hours stirring at 0-10° C., water (100 ml) was added and then the reaction mixture was extracted with Methylene chloride. The Methylene chloride layer was dried over Sodium sulphate and distilled off to give a crude mass which was purified by column chromatography using 7% Ethyl acetate in Hexane (9.0 gm).
