Methyl Salicylate → Methyl 2-(oxiran-2-ylmethoxy)benzoate

참여 물질

반응 단계

A mixture of 15.2 g (0.10 mole) of methyl 2-hydroxybenzoate, 27.6 g (0.20 mole) of potassium carbonate and 31 ml (0.40 mole) of epichlorohydrin in 250 ml of acetone was heated to reflux for 24 hours. The reaction medium was then filtered and evaporated under reduced pressure. The resulting oil was dissolved in 100 ml of toluene and washed consecutively with 100 ml of water, 2×100 ml of 1.0N sodium hydroxide and 2×100 ml of water. The organic phase was then dried over magnesium sulfate and evaporated under reduced pressure to provide the crude product as an oil. Purification was effected by vacuum distillation to provide an oil in 12% yield: boiling point 148° C. (75μ). The NMR and IR spectra and elemental analysis were consistent with the assigned structure.
