Acetic Acid → Methyl 4-((3-((phenylamino)methyl)phenoxy)methyl)benzoate

To a stirred solution of methyl 4-((3-formylphenoxy)methyl)benzoate (464 mg, 1.72 mmol) in anhydrous DCM (8 mL) was added aniline (0.63 mL, 6.87 mmol) followed by glacial acetic acid (0.46 mL, 6.87 mmol). The reaction was stirred at room temperature for 18 hours. Sodium triacetoxyborohydride (1.52 g, 6.87 mmol) was added and the reaction was stirred at room temperature for 2 hours. The mixture was diluted with DCM (100 mL). The organic layer was washed with 1 N HCl (3×30 mL) and saturated aqueous NaHCO3 (30 mL) and passed through a hydrophobic fit. The solvent was removed in vacuo to afford the title compound as an oil that solidifies on standing (380 mg, 64% yield).
