Reaktionsschritte

1 g of 9-methoxymethyl-9-hydroxymethyl-fluorene (4.2 mmol) was dissolved in 20 ml of dichloromethane. The solution was cooled in ice-water bath, and 0.87 ml of triethyl amine (6.2 mmol) was added thereto. After stirring for 5 minutes, 0.91 ml of triethylsilyl chloride (5.4 mmol) 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 1.24 g of concentrate (yield 84%).
