実験手順: To 3-fluoro-2-methoxyaniline (2.8 g, 20 mmol) in 10 mL of acetic acid was added bromine (0.82 mL, 16 mmol) in acetic acid (10 mL) dropwise. The reaction mixture was stirred at rt. for 30 min. Solid was filtered and washed with acetic acid to give the HBr salt. It was then dissolved in water, basified by addition of KOH, extracted with ethyl acetate. The organic layer was dried and concentrated to give a white solid (2.8 g, 80%). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 3.93 (s, 3H) 6.42 (dd, J=8.6, 1.8 Hz, 1H) 7.01 (dd, J=8.6, 7.1 Hz, 1H). [M+H] calc'd for C7H7BrFNO, 222. found 222. Solid was filtered washed with acetic acid

実験手順: To a solution of 2-methoxy-3-fluoroaniline (2.18 g, 15.46 mmol) in AcOH (10 mL) was added a solution of bromine (1.98 g, 12.37 mmol) in AcOH (2 mL) dropwise. The reaction mixture was stirred at room temperature for 30 minutes. The resulting solid was filtered and washed with acetic acid to give the title and a di-bromo-compound as the HBr salt. The solid (2.53 g) was dissolved in water, basified by addition of KOH, and extracted with EtOAc. The organic layer was dried with Na2SO4 and concentrated in vacuo. The residue was purified by Biotage silica gel column chromatography eluting with 15% EtOAc in cyclohexanes to give the title compound as white solid (1.24 g, 36%). The resulting solid was filtered washed with acetic acid to give the title extracted with EtOAc The organic layer was dried with Na2SO4 concentrated in vacuo The residue was purified by Biotage silica gel column chromatography eluting with 15% EtOAc in cyclohexanes
