Versuchsvorschrift
(4-Chloro-3-(trifluoromethyl)phenyl)methanol (5.1 g, 24.22 mmol) was added in small portions to thionyl chloride (20 mL, 275 mmol). The reaction mixture was stirred at 50° C. for 18 h and heated under reflux for 23 h. The mixture was concentrated and dried under high vacuum to give the title compound as a colorless liquid (5.41 g). 1H NMR (400 MHz, CDCl3) δ ppm 4.58 (s, 2H), 7.50-7.51 (m, 2H), 7.71 (s, 1H).
