[3-(4-Chloro-[1,3,5]triazin-2-ylamino)phenyl]acetic acid methyl ester (3.530 g, 12.67 mmol) is combined with 2-chlorobenzimidazole (1.933 g, 12.67 mmol) and K2CO3(2.101 g, 15.20 mmol) in AcCN (50 ml) and heated at 65-750° C. for 2 to 20 hours. The reaction mix is cooled to RT. The inorganic salts are filtered off. The AcCN solution is concentrated down under reduced pressure. The crude is purifired by chromatography with an EtOAc/hexane elution gradient, giving {3-[4-(2-chloro-benzimidazol-1-yl)-[1,3,5]triazin-2-ylamino]phenyl}acetic acid methyl ester.
