Versuchsvorschrift
To 4-ethylaniline (1.76 g, 14.52 mmol) and NBS (2.58 g, 14.52 mmol) was added DMF (67 mL) and the reaction mixture was stirred at 0° C. for 10 min. The reaction mixture was purified by silica gel chromatography (0-50% ethyl acetate/hexanes) to provide 2-bromo-4-ethylaniline (2.7 g, 93% yield). LC/MS m/z 201.0 [M+H]+.
