実験手順

4,6-Dichloro-N-(3-trifluoromethyl-4-fluorophenyl)-1,3,5-triazine-2-amine (XVII) (2.0 g, 6.2 mmol) was dissolved in dioxane (40 mL). Diisopropylethyl-amine (1.6 mL, 9.32 mmol) was added followed by [4-(trifluoromethoxy)-benzylidene]hydrazine (XX) (1.3 g, 6.2 mmol). The reaction was stirred at room temperature overnight. The solvent was removed under vacuum, and the residue diluted with ethyl ether (25 mL). The organic phase was washed with brine, dried over magnesium sulfate, filtered and concentrated to a yellow powder. This powder was washed with acetonitrile to give {4-chloro-6-[N′-(4-trifluoromethoxy-benzylidene)hydrazino]-1,3,5-triazin-2-yl}-(4-fluoro-3-trifluoromethylphenyl)-amine (XXI) as a white solid; (2.1 g, 67% yield): m.p. 109-111° C.; 1H NMR (CDCl3): δ 8.9, (bs, 1H); 8.5 (bs, 1H); 7.95 (s, 1H); 7.75 (bs, 2H); 7.45 (bs, 1H); 7.24 (m, 4H); ESI/MS 494 (M+H).
