Ethanol → Ethyl 2-(3,5-difluorophenyl)acetate

Participants

Reaction Steps

5 g of 3,5-difluorophenylacetic acid are dissolved in 50 ml of ethanol and 3 ml of concentrated H2SO4, and the mixture is heated at reflux for two hours. The mixture is evaporated to dryness, neutralization is then carried out with a saturated K2CO3 solution, extraction is then carried out with AcOEt and the organic phase is evaporated to produce 5.0 g of the expected compound in the form of a colourless liquid.
