Dichloromethane → 9,9-Bis(trimethylsilyloxymethyl)fluorene

참여 물질

반응 단계

1 g of 9,9-bis(hydroxymethyl)-fluorene was admixed with 20 ml of dichloromethane. The mixture was cooled in ice-water bath, and 1.9 ml of triethyl amine was added thereto. Then 1.4 ml of trimethylsilyl chloride was added drop-wise, and the mixture was stirred in ice-water bath for further 2 hours. 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 88%). The crude product was purified by column chromatography using petroleum ether as eluent, to give colorless pure compound. MS (El) m/e: 370(M+).
