Reaktionsschritte
A solution of 2-acetyl-5-(4-fluorobenzyl)furan (10 g, 46 mmol) and trimethylsilylacetic acid ethyl ester (10.9 g, 68 mmol) in anhydrous THF (30 ml) was cooled at −20° C. To a solution was added anhydrous tetrabutylammoniumfluoride (0.2 g). The reaction mixture was gradually warmed up to room temperature and stirred for 15 minutes at 50° C. The THF was evaporated under reduced pressure. The residue was distilled under reduced pressure. The fraction showing b.p. 130° C. (0.5 mmHg) was collected to give [1-[5-(4-fluorobenzyl)furan-2-yl]vinyloxy]-trimethylsilane (11.7 g). Yield 88%.
