Procedure

To a chilled suspension of 3-aminobenzyl alcohol (9.24 g, 75 mmol) in THF (50 mL) was added neat acetic anhydride (8.1 mL, 86 mmol). The reaction mixture was stirred cold for 1 hr, diluted with EtOAc, washed with aq. NaOH and brine, and concentrated in vacuo to give N-[3-(hydroxymethyl)phenyl]acetamide (10.5 g, 85%).
