الإجراء التجريبي

To a solution of compound 18a (1.0 g, 4.9 mmol) in anhydrous NMP (10 ml) was added triethylamine (0.68 ml, 4.9 mmol) and compound 17a (0.68 ml, 4.91 mmol) and the resultant mixture was stirred at 100° C. over night. The cooled reaction mixture was poured into ice-water and the precipitate was filtered off, re-dissolved in dichloromethane, dried over magnesium sulphate and concentrated in vacuo. This concentrate was triturated in a mixture of diethyl ether and petroleum ether to afford 19a as a brownish solid (1.2 g, 62%). The following compounds were prepared in analogy herewith: [3-(2-Ethyl-2H-[1,2,4]triazol-3-ylmethoxymethyl)-phenyl]-(2-nitro-4-trifluoromethylphenyl)-amine (19b) from 17a and 18b. Yield: 78% (4-Methyl-2-nitro-phenyl)-[3-(2-methyl-2H-[1,2,4]triazol-3-ylmethoxymethyl)-phenyl]-amine (19c) from 17b and 18a. Yield: 20% 1-{4-[3-(2-Methyl-2H-[1,2,4]triazol-3-ylmethoxymethyl)-phenylamino]-3-nitro-phenyl}-ethanone (19d) from 17c and 18a. Yield: 74%
