To a solution of 2-(5,6-Dimethoxy-benzoimidazol-1-yl)-4-phenyl-thiazole-5-carboxylic acid (30 mg, 0.075 mmol) in dimethylformamide (1 ml) was added diethylisopropylamine (15.6 μL, 0.09 mmol) and HATU (28.5 mg, 0.075 mmol). The mixture was stirred under ambient temperature for 5 min. Aniline (6.8 μL, 0.075 mmol) was added. The mixture was stirred for 1 hr. Ethyl acetate (5 ml) was added. The mixture was washed with water (2×3 ml), brine, dried with magnesium sulfate and concentrated in vacuo. The crude was purified with flash chromatography (0 to 2% methanol dichloromethane) to afford 2-(5,6-Dimethoxy-benzoimidazol-1-yl)-4-phenyl-thiazole-5-carboxylic acid phenylamide (30 mg, 86.4%) as a yellow solid. MS m/z 457 (M+1).
