Procedure

A 20 mL flask was charged with N-(6-chloropyridin-3-yl-methyl)-N′-(4-fluoro-3-trifluoromethylphenyl)-6-hydrazino-1,3,5-triazine-2,4-diamine (XIX) (285 mg, 0.66 mmol), 4-(trifluoromethoxy)benzaldehyde (251 mg, 1.32 mmol), and ethanol (10 mL), and the resulting mixture stirred at ambient temperature for 24 h. The mixture was concentrated under vacuum, the residue washed with hexanes and recrystallized from hexanes-ethyl ether to afford the titled compound (2) as a white solid (182 mg, 45% yield): m.p. 117-125° C.; 1H NMR (CDCl3): δ 8.65 (bs, 1H); 8.54 (d, J=4.5 Hz, 1H); 8.35 (bs, 1H); 7.84 (s, 1H); 7.73 (d, J=7.2 Hz, 2H); 7.49-7.7 (m, 4H); 7.26 (m, 3H); 7.2 (t, J=6.0 Hz, 1H); 4.66 (d, J=6.0 Hz, 2H); Anal. Calcd for C24H17F7N8O: C, 50.89, H, 3.03, N, 19.78. Found C, 50.49; H, 3.17; N, 19.31
