49 (3-Bromophenyl)methanol
Example 49 (3-Bromophenyl)methanol Sodium borohydride (7.1 g, 186.1 mmol) in several portions was added to a solution of 3-bromobenzaldehyde (114.8 g, 620.4 mmol) in EtOH (650 mL) at 25° C. Then the mixture was stirred for 1 h at room temperature. The reaction was quenched with water (200 mL). After removing EtOH, the residue was dissolved in AcOEt (500 mL), and filtered. The filtrate was washed with water (150 mL), brine (150 mL), and dried over Na2SO4. After removing the solvent, 115.8 g of the title compound was obtained (yield: 99.8%).
