反应详情

To a solution of 1.70 g of 3-chloro-2-methylbenzoic acid in 20 mL of THF was added dropwise 20 mL of a borane/THF complex under ice-cooling, followed by stirring at room temperature for 2 hours. After completion of the reaction, 1 N hydrochloric acid was added to the reaction liquid, followed by extraction with chloroform. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate and then concentrated under reduced pressure to obtain 1.52 g (yield 97%) of a title compound as a white crystal.
