Versuchsvorschrift

This compound was produced using similar methods as those used in Step 5, example 27, starting with 2-(3,5-bis-trifluoromethyl-benzoylamino)-4-(3-bromo-propoxy)-benzoic acid methyl ester (0.35 g, 0.66 mmol), 4-trifluoromethyl-benzaldehyde oxime (0.13 g, 0.70 mmol) and cesium carbonate (0.86 g, 2.65 mmol) in acetone (25 mL). The crude material was purified by flash chromatography through silica gel using diethyl ether/hexanes (0/100 gradient to 10/90) to give 2-{[3,5-bis(trifluoromethyl)benzoyl]amino}-4-{3-[({(1E)-[4-(trifluoromethyl)phenyl]methylidene}amino)oxy]propoxy}benzoic acid methyl ester (0.33 g, 78%) as a white solid. 1H NMR (500 MHz, DMSO-d6); δ 11.78 (s, 1H), 8.51 (s, 2H), 8.45 (s, 1H), 8.37 (s, 1H), 8.10 (d, 1H), 7.97 (d, 1H), 7.79-7.71 (AA′BB′, 4H), 6.88 (dd, 1H), 4.34 (t, 2H), 4.22 (t, 2H), 3.85 (s, 3H), 2.18 (m, 2H).
