Imidazole → tert-Butyl[(furan-2-yl)methoxy]dimethylsilane

Participants

Reaction Steps

To a 1 liter flask containing dimethyl formamide (150 mL) was added furfuryl alcohol (17.7 mL, 0.20 mol), t-butyldimethylsilyl chloride (33.7 g, 0.22 mole), and imidazole (15.3 g, 0.22 mol). After 22 hours stirring at RT, the reaction was filtered and the volatiles removed in vacuo. The resulting material was partitioned between diethyl ether (500 mL) and a saturated aqueous solution of citric acid (100 mL). Additionally, the ether layer was washed 2×100 mL sat. citric acid. The combined aqueous layers were back extracted 1×50 mL ether. The combined organic layers were washed 1×100 mL water followed by 1×100 mL brine. The ether layer was dried over anhydrous sodium sulfate, filtered, and evaporated to yield 28.1 g (65% yield). 1H NMR: (DMSO-d6) δ 0.01 (s, 6H), 0.82 (s, 9H), 4.55 (s, 2H), 6.29 (d, 1H), 6.36 (dd, 1H), 7.58 (d, 1H)
