Reaction Steps

A mixture of methyl 3-bromo-5-formylbenzoate (200 mg, 0.82 mmol), methanol (3 mL), 2.0 M dimethylamine solution in THF (0.3 mL, 6 mmol), zinc dichloride (30 mg, 0.22 mmol), and sodium cyanoborohydride (200 mg, 3.2 mmol) was stirred at 0° C. for 1 h. The mixture was diluted with water (10 mL) and the aqueous layer was extracted with EtOAc (15 mL×3). The combined organic layers were dried over anhydrous MgSO4 and concentrated. The residue was purified by silica gel chromatography to afford the title compound.
