Versuchsvorschrift

To [2-bromo-5-(trifluoromethyl)phenyl]methanol (4.4 g, 17 mmol) was added thionyl chloride (5 mL) and the resulting mixture was stirred at room temperature for 1 h. Evaporation in vacuo gave the crude product as an oil. 1H NMR (CDCl3) δ 7.77 (d, J=8.3 Hz, 1H), 7.73 (d, J=2.0 Hz, 1H), 7.53 (dd, J=8.5, 2.2 Hz, 1H), 5.66 (d, J=12.7 Hz, 1H), 5.46 (d, J=12.2 Hz).
