反应详情

In a round-bottom flask were placed 10 g of 9-((2R, 3R, 4S)-3,4-bis-hyroxymethyl-oxetan-2-yl)-adenine and 100 mL of pyridine. To the system was added 6.4 g of tert-butylchlorodimethylsilane, and the reaction mixture was stirred under nitrogen at room temperature for 1 day. The mixture was diluted with ethyl acetate and washed with saturated aqueous sodium bicarbonate and brine, dried (sodium sulfate) and concentrated with a rotary evaporator. The residue was purified by column chromatography to afford 9-((2R,3R,4S)-4-t-butyldimethylsiloxymethyl-3-hydroxymethyl-oxetan-2-yl)adenine.
