Reaction Steps

A solution of 10.0 g of 6-fluoro-3,3-dimethyl-1-indanone, 11.1 ml of 3-buten-2-ol and 200 mg of p-toluenesulfonic acid in 200 ml of 2,2-dimethoxypropane was boiled under reflux for 96 hours on a water separator filled with molecular sieve (0.4 nm, 2 mm pearl shaped). The reaction mixture was subsequently concentrated in a vacuum and purified by column chromatography on silica gel (hexane/ethyl acetate 8:1). In addition to 11.9 g of educt, there were obtained 3.38 g (26%) of (RS)-2-(2-buten-1-yl)-6-fluoro-3,3-dimethyl-1-indanone as a yellow oil.
