Versuchsvorschrift

Prepared according to Procedure A using 3-trifluoromethylanthranilic acid (2.0 g, 9.75 mmol) and SOCl2 (1.8 mL, 24.4 mmol) in benzene (50 mL), followed by 2-chloroaniline (2.1 mL, 19.5 mmol) and CHCl3 (50 mL). The product was purified by recrystallization from MeOH to provide 2.38 g yellow crystals (78%). 1H NMR (CDCl3) δ: 8.40 (dd, J=1.4, 8.3 Hz, 1H); 8.25 (br s, 1H); 7.71 (d, J=7.8 Hz, 1H); 7.60 (d, J=7.8 Hz, 1H); 7.43 (dd, J=1.4, 8.0 Hz, 1H); 7.34 (dt, J=1.3, 7.9 Hz, 1H); 7.11 (dt, J=1.5, 7.7 Hz, 1H); 6.77 (t, J=7.8 Hz, 1H); 6.24 (br s, 2H). MS (ES): m/z 315.0 (M+).
