실험 절차
a solution of 270 mg of 1-[bis(dimethylamino)methylidene]-2,3-dihydro-1H-[1,2,3]triazolo[4,5-b]pyridin-1-ium-3-oxide hexafluorophosphate, 61 mg of cyclopropanecarboxylic acid and 176 mg of diisopropylethylamine in 40 cm3 of N,N-dimethylformamide is stirred for one hour at a temperature close to 20° C. Then 250 mg of 6-[(2,6-dichlorobenzyl)oxy]-1H-benzimidazol-2-aminium trifluoroacetate is added and the orange solution obtained is stirred for about twenty hours at about 20° C. After concentration under reduced pressure (0.2 kPa), the residue is taken up in 40 cm3 of water and the mixture obtained is extracted three times with 40 cm3 of ethyl acetate. The combined organic phases are washed three times with 40 cm3 of water, then dried over magnesium sulphate, filtered and concentrated under reduced pressure. After purification of the residue by flash chromatography on silica [eluent: dichloromethane/methanol (95/5 by volume)], we obtain 64 mg of N-{6-[(2,6-dichlorobenzyl)oxy]-1H-benzimidazol-2-yl}cyclopropanecarboxamide in the form of a white powder, which has the following characteristics:
