Procedure
144 g of 3-fluoro-6-(phenylthio)-benzoic acid in 1000 ml of tetrahydrofuran is treated dropwise under a nitrogen atmosphere and under reflux with a 70% sodium-dihydro-bis(2-methoxyethoxy)-aluminate solution in benzene. The mixture is held under reflux for a further 2 hours. After the addition of 400 ml of benzene, the mixture is cooled to 20° C, acidified with 435 ml of 3-N hydrochloric acid and subsequently treated with 600 ml of concentrated hydrochloric acid. The organic phase is washed with water, dried over sodium sulphate and evaporated. There is obtained 3-fluoro-6-(phenylthio)-benzyl alcohol as a thick oil.
