A mixture of tert-butyl(3-hydroxyphenyl)(phenyl)methylcarbamate (3.20 g, 10.7 mmol), methyl 4-(bromomethyl)benzoate (2.70 g, 11.8 mmol), and potassium carbonate (2.20 g, 16.1 mmol) in acetonitrile (54 mL) was stirred at room temperature for 16 hours. The reaction mixture was concentrated at reduced pressure, and the residue partitioned between ethyl acetate and water. The aqueous phase was extracted with further ethyl acetate, and the combined organic extracts combined, dried with anhydrous magnesium sulfate, filtered and the solvent evaporated at reduced pressure. The residue was re-crystallised from ethyl acetate and iso-hexane to afford the title compound (3.25 g, 68%).
