反応手順

To the clear solution of 4-Hydroxy-7-methoxy indane (2.0 gm, 0.0121 mole) in Acetone (20 ml), Potassium carbonate (2.52 gm, 0.0182 mole) was added at room temperature and stirred for 1.5 hours. A solution of 2-Bromo-1-thiophene-2-yl-ethanone (3.75 gm, 0.0181 mole) in Acetone (10 ml) was added at 0° C. and stirred for 8 hours at room temperature. The reaction mixture was poured into the water (50 ml) and extracted with Ethyl acetate (2×100 ml). The Ethyl acetate layer was dried over Sodium sulphate and evaporated to give a crude product which was purified by column chromatography using 2% Ethyl acetate in hexane as a mobile phase The collected eluent was evaporated to yield desire product (2.1 gm) as an viscous oil.
