Versuchsvorschrift
To a solution of 4-bromo-2-methansulfonyl-benzaldehyde (1.0 g, 3.88 mmol) in EtOH (11 mL)/THF (2.5 mL) was added NaBH4 (1.29 g, 34.2 mmol) in three portions. The reaction was carefully quenched with water and the product was extracted with EtOAc, dried (Na2SO4), and purified by silica gel chromatography to give 735 mg of (4-bromo-2-methansulfonyl-phenyl)-methanol.
