Vorschrift

A mixture of 4-[1-(3-methoxy-4-hydroxyphenacyl)-1H-benzimidazol-2-yl]-furazan-3-ylamine (0.10 g, 0.27 mmol), DIPEA and methoxymethyl chloride in dry DMF is stirred at room temperature for 14 hours. The reaction mixture is diluted with ethyl acetate, washed with water and dried over sodium sulphate. Filtration of the sodium sulphate and concentration of the filtrate under reduced pressure gives the title compound as colorless, pure solid, m.p. 190° C.
