Procedure

To [5-(2-amino(4-pyridyloxy))-1-methylbenzimidazol-2-yl](4-chlorophenyl)amine (1 eq) in tetrahydrofuran added EDC (2 eq) and HOAT (1 eq) and N,N-disopropylethylamine (4 eq) and benzoic acid (1 eq) and the resulting mixture was stirred at ambient temperature for 16 h. The reaction mixture was then partitioned between ethyl acetate and water. The organic layer was then dried with sodium sulfate and concentrated and purified by preparative chromatography to to give N-[4-({2-[(4-chlorophenyl)amino]-1-methyl-1H-benzimidazol-5-yl}oxy)pyridin-2-yl]benzamide. MS: MH+=470.9.
