Reaktionsschritte

2-hydroxy-2-(2-hydroxy-4-isopropyl-phenyl)-indan-1,3-dione (1.00 g, 3.37 mmol) was completely dissolved in anhydrous methylene chloride (20 ml). This solution was added with benzoyl chloride (0.94 g, 6.74 mmol), triethylamine (0.41 g, 4.04 mmol), and DMPA (0.01 g), followed by heating 24 hrs under reflux. After the reaction mixture was concentrated, extracted with dichloromethane, and the organic layer was concentrated and purified using column chromatography (ethylacetate:hexane=1:4) to afford the title compound (0.81 g, 14%).
