실험 절차

5-Fluoro-2-methylaniline (10.0 g, 79.9 mmol, 1 equiv) was dissolved In toluene (50 mL) and placed in a cool water bath. Acetic anhydride (11.3 mL, 120 mmol, 1.5 equiv) was added slowly. After 15 minutes, a white precipitate had formed. The solid was collected by filtration and washed with toluene several times, affording 10.93 g (82%) of the title compound as a white crystalline solid. MS (ES+) m/e 213 [M+H].
