Procedure
To a stirred solution of 4-aminomethylphenol (1 g, 8.13 mmol) in tetrahydrofuran/water (1:1 ratio, 20 ml) at 0° C. was added solid NaHCO3 (0.888 g, 10.16 mmol) followed by dropwise addition of benzyl chloroformate (1.16 ml, 8.13 mmol). The mixture was stirred at 0° C. for 10 minutes then allowed to warm slowly to r.t. After stirring the mixture for 90 minutes the tetrahydrofuran was removed in vacuo. The aqueous layer was extracted with EtOAc (2×10 ml). The organic layer was washed with water (2×10 ml), dried (MgSO4), and the solvent removed in vacuo to a residue. Trituration with heptane gave the product as a white solid (2.10 g, 100% yield). LCMS purity 100%, m/z 258 [M++H]−.
