Preparation Example 4(5-Bromo-2-fluorophenyl)methanolTo a solution of 5-bromo-2-fluorobenzaldehyde (30.0 g, 148 mmol) in EtOH was added sodium borohydride (8.39 g, 222 mmol) at 0 °C. The resulting mixture was stirred with gradual warming to ambient temperature over 15 h, re-cooled to 0 °C, and quenched with aq. saturated NH₄C1 solution. The mixture was extracted with EtOAc. The organic layer was washed with brine, dried over MgS0₄, filtered and evaporated in vacuo to yield the titled compound (30.3 g, quantitative) as a white sold, which was carried on to the next step without further purification.[M-OH^"]+ 187.
