[3-(4-Bromo-2-formyl-phenoxy)-phenyl]-acetic acid methyl ester (0.151 g, 0.43 mmol), benzylamine (0.05 mL, 0.48 mmol), and sodium cyanoborohydride (0.041 g, 0.65 mmol) were combined in CH2Cl2 (3 mL). Acetic acid (2 drops) was added, and the reaction was stirred overnight at room temperature. The mixture was partitioned between CH2Cl2 and saturated aqueous NaHCO3, and the aqueous layer was separated and extracted twice with CH2Cl2. The combined organic layers were dried over MgSO4 and concentrated, and the residue was purified by silica gel chromatography (10-30% EtOAc in hexanes) to give the title compound.
