Methyl 3-{[(tert-butoxycarbonyl)amino]methyl}benzoate (4.6 g) was mixed with toluene (50 ml), followed by cooling to 0° C. Sodium bis(2-methoxyethoxy)aluminum hydride (65% toluene solution) (20 g) was added dropwise over 30 minutes, followed by stirring at 0° C. for 1 hour. A 1 M aqueous NaOH solution (30 ml) was added dropwise to the reaction mixture, and CHCl3 was then added thereto. The organic layer was dried over Na2SO4 and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/EtOAc) to obtain tert-butyl [3-(hydroxymethyl)benzyl]carbamate (4.1 g).
