Reaction Steps

Sodium tetrahydroborate (0.31 g, 8.1 mmol) was added to a mixture of 1-(3-bromo-5-chloro-2-methoxy-4-methylphenyl)ethanone (1.5 g, 5.4 mmol) in methanol (25 mL) at 0° C. and the resultant reaction mixture was stirred at room temperature for 1 hour. The solvent was removed and the resulting residue was diluted with ethyl acetate, washed with sat. NaHCO3, water, brine, then dried over Na2SO4, filtered and concentrated. The crude product was purified by silica gel chromatography, eluting with 0 to 40% EtOAc in hexanes, to give the desired product (0.30 g, 90%).
