A mixture of 5-nitro-2-phenoxy-benzoic acid methyl ester (4.0 g, 14.7 mmol) and hydrazine (5 mL, 80%) was refluxed for 4 h to yield 5-nitro-2-phenoxy-benzoic acid hydrazide (2.97 g, 74%). The title compound was prepared from 5-nitro-2-phenoxy-benzoic acid hydrazide and 3-trifluoromethyl-benzaldehyde by a procedure similar to Example 22. 1H NMR (DMSO-d6): 12.20 (s, 1H), 8.52 (s, 1H), 8.43 (s, 1H), 8.35 (d, J=7.2 Hz, 1H), 8.17 (s, 1H), 8.10 (d, J=6.6 Hz, 1H), 7.81 (m, 1H), 7.75 (t, J=6.6 Hz, 1H), 7.54 (t, J=7.2 Hz, 1H), 7.35 (m, 2H), 7.27 (d, =J=7.2 Hz, 1H), 7.03 (m, 2H).
