Triethylamine → 3-fluoro-N-(3-iodo-4-methylphenyl)-5-(trifluoromethyl)benzamide

Temperatur

0 °C

3-Iodo-4-methylaniline (2.42 g, 10.4 mmol) was dissolved in DCM (20.00 mL) and triethylamine (TEA) (1.70 mL, 12.2 mmol) was added and the resulting mixture was cooled to 0° C. To the mixture was added dropwise 3-fluoro-5-(trifluoromethyl)benzoyl chloride (1.60 mL, 10.5 mmol) and the resulting mixture was stirred at 0° C. for 45 minutes and at 25° C. for 16 hours. The reaction was extracted with ethyl acetate and the organic extracts were washed with water sat. Na2CO3, saturated NaCl, dried (MgSO4) and concentrated in vacuo. The reaction product was used in the next reaction without purification. 1H NMR (CDCl3): 8.98 (d, 1H), 7.78 (s, 1H), 7.72 (m, 2H), 7.55 (m, 2H), 7.23 (d, 1H), 2.42 (s, 3H). MS (EI) m/z=424 (M+H).
