Reaction Steps

To 1.0 g of lithium aluminium hydride in 120 ml of dry ether, at room temperature is added dropwise 5.4 g (0.02 moles) of ethyl-1-(4-ethoxyphenyl)-2,2-difluorocyclopropane-1-carboxylate in 20 ml of ether. The reaction mixture is stirred for 1 hr after which 1.0 ml of water 1.0 ml of 15% NaOH, followed by 3.0 ml of water are added. The solid precipitate is filtered off, washed with ether and the combined filtrates dried and concentrated under reduced pressure to yield (4.2 g) a colourless oil; nD 1.5129.
