In a 100 mL round bottomed flask equipped with a stir bar was placed 3-bromo-2-fluoro-4-methoxy-benzaldehyde (I-30, 1.67 g, 7.17 mmol), methanol (12 mL), dichloromethane (12 mL) and sodium borohydride. The reaction mixture was allowed to stir at room temperature for 17 hours, quenched with water (10 mL) and 1M HCl (5 mL) and extracted with dichloromethane (2×30 mL). The organic portions were combined, washed with brine (30 mL), dried (MgSO4) and concentrated. The crude material was triturated with hexanes (15 mL) to produce 955 mg (57%) of (3-bromo-2-fluoro-4-methoxy-phenyl)-methanol (I-31) as a white solid.
