Versuchsvorschrift

Into a solution of 1.0 g (5.40 mmol) of 3-bromo-4-methylaniline and 0.91 mL (6.50 mmol) of triethylamine in 10 mL THF at 0° C. was slowly added 0.68 mL (6.50 mmol) of 2-methylpropanoyl chloride. The reaction mixture was stirred at room temperature for 2 hours and concentrated in vacuo. The residue was dissolved in CH2Cl2 and washed with H2O, followed by brine. The organic layer was dried over MgSO4 and concentrated in vacuo to give 1.37 g (5.35 mmol, 99%) of the desired product: ESMS m/e: 255.9 (M+H)+.
