실험 절차

To a solution of 26.8 g of the 2,2,4,6,7-pentamethylindan-5-carboxaldehyde in 93 ml of absolute acetone was added 46 ml of water and 50 g of 2% NaOH. After refluxing for 20 hours, the solution was acidified with 2N HCl and extracted with diethyl ether. The organic layer was dried over anhydrous magnesium sulfate, filtered and evaporated under reduced pressure. The residue was purified by silica-gel column chromatography to afford 25.36 g of the title compound as yellow solid.
