Reaction Steps

5.0 g of ethyl 3,5-difluorophenylacetate are dissolved in 50 ml of ethyl formate. 2.0 g of 60% NaH are added portionwise. The mixture is poured onto a 1N HCl solution and then extraction is carried out with AcOEt. The residue is triturated in petroleum ether, the remaining white precipitate is filtered off and then the filtrate is evaporated to produce 3.3 g of the expected compound in the form of a liquid.
