Vorschrift

To N-{4-[(2-{[2-fluoro-5-(trifluoromethyl)phenyl]amino}-1-methyl-1H-benzimidazol-5-yl)oxy]pyridin-2-yl}piperidine-4-carboxamide (1 eq) in dioxane and N,N-disopropylethylamine (2 eq) was added acetic anhydride (1 eq) and the resulting mixture was stirred for 1 h. 1-acetyl-N-{4-[(2-{[2-fluoro-5-(trifluoromethyl)phenyl]amino}-1-methyl-1H-benzimidazol-5-yl)oxy]pyridin-2-yl}piperidine-4-carboxamide thus formed was purified by preparative chromatography. MS: MH+=571.5.
