Water → (5-Bromo-2-chlorophenyl)methanol

A solution of methyl 5-bromo-2-chlorobenzoate (9.23 g) in THF (50 ml) was added dropwise under ice-cooling to a suspension of lithium aluminum hydride (1.42 g) in THF (100 ml). After the completion of addition, the reaction mixture was stirred at room temperature for 45 minutes. Water (1.4 ml), 5N sodium hydroxide solution (1.4 ml) and water (4.2 ml) were sequentially added under ice-cooling to the reaction mixture. The precipitate was removed through Celite and the filtrate was concentrated under reduced pressure to obtain a title compound (7.56 g).
