Methyl 2-[2-(tetrahydropyran-2-yloxy)-phenyl]-3-fluoromethoxy-acrylate → Methyl 2-(2-hydroxyphenyl)-3-fluoromethoxy-acrylate

Participants

Reaction Steps

6.2 g (0.02 mol) of methyl 2-[2-(tetrahydropyran-2-yloxy)-phenyl]-3-fluoromethoxy-acrylate are stirred in 30 ml of methanol at 20° C. for 18 hours with 0.5 g of acidic ion exchanger. The ion exchanger is filtered off and the filtrate is concentrated. The residue is chromatographed on silica gel using hexane/acetone (7:3). 3.3 g (73% of theory) of methyl 2-(2-hydroxyphenyl)-3-fluoromethoxy-acrylate are obtained as a pale yellow, viscous oil.
