Lithium aluminium hydride (4.6 g) was added in small portions to a stirred solution of 2,3,5,6-tetrafluorobenzoic acid (30.0 g) in dry ether (600 ml) at the ambient temperature, and stirring continued for a period of 3 hours. After decomposition of the excess lithium aluminium hydride with ethyl alcohol, water was added in excess and the ethereal phase separated, washed with water, and concentrated to yield crude 2,3,5,6-tetrafluorobenzyl alcohol (13.0 g) as a colourless oil.
