실험 절차

1 g of 9-methoxymethyl-9-hydroxymethyl-fluorene was dissolved in 20 ml of dichloromethane. The solution was cooled in ice-water bath to below 5° C., and 0.7 ml of triethyl amine was added thereto. After stirring for 5 minutes, 0.6 ml of trimethylsilyl chloride was added drop-wise, and the mixture was stirred for further 2 hours, followed by stirring at room temperature for 1 hour. The reaction mixture was washed with water, and the organic layer separated was dried over anhydrous sodium sulfate. After filtration, the filtrate was evaporated to give 1.41 g of concentrate (yield 86%). MS(EI) m/e: 312(M+).
