Participants

Reaction Steps

To a solution of 17.7 g of the 2-ethyl-2,4,5,7-tetramethylindane in 100 ml of dry dichloromethane was continuously added 9.5 ml of α,α-dichloromethyl methyl ether and 11.6 ml of TiCl4 at 0° C. The reaction mixture was stirred at room temperature for 2 hours, quenched with 200 ml of water, and separated the organic layer. The aqueous layer was extracted with dichloromethane. The combined organic layer was dried over magnesium sulfate, filtered and evaporated under reduced pressure. The residue was purified by silica-gel column chromatography to afford 18.26 g of the title compound as brown solid.
