Procedure

3-(t-Butyloxycarbonylamino)benzoic acid sodium salt (10 g), DMF (60 ml) and potassium iodide (6.3 g) are mixed, and thereto is added dropwise pivaloyloxymethyl chloride (6 g) under ice cooling. The mixture is stirred at room temperature for 15 hours, and thereto is added ethyl acetate (200 ml). The mixture is washed with water, and ethyl acetate is distilled off under reduced pressure. The residue is recrystallized from 70% aqueous acetonitrile to give pivaloyloxymethyl 3-(t-butyloxycarbonylamino)benzoate (11.9 g).
