Reaktionsschritte

4-Bromo-2-ethyl-aniline (2 mL, 14 mmol) dissolved in anhydrous pyridine (35 mL) at toom temperature was treated with methylsulfonyl chloride (1.3 mL, 16.8 mmol). The reaction was stirred at that temperature for 15 hours before it was diluted with EtOAc. The mixture was washed with H2O, brine and dried over MgSO4. The solvent was removed in vacuo and the residue was purified with flash chromatography (SiO2, 5-30% EtOAc in hexanes) to afford the desired product (3.1 g, 81% yield). 1H NMR (300 MHz, CDCl3): δ 1.25 (t, J=7.5 Hz, 3H), 2.61-2.68 (m, 2H), 3.02 (s, 3H), 6.36 (s, 1H), 7.36-7.39 (m, 3H).
