Procedure:
To a 100 mL round bottomed flask was added 2-(4-(benzo[d]thiazol-2-ylamino)phenoxy)nicotinic acid (0.3031 g, 0.834 mmol), cyclopropylmethanamine (0.0869 g, 1.22 mmol), and triethylamine (0.347 mL, 2.50 mmol) in N,N-dimethylformamide (3 mL) to stir for 5 min. HATU (0.3955 g, 0.917 mmol) was then added and allowed to stir overnight. The reaction mixture was diluted with water (10 mL) and extracted with DCM (3×10 mL). The organic extract was washed with water (1×10 mL), saturated sodium chloride (1×10 mL), saturated sodium bicarbonate (1×10 mL), dried with magnesium sulfate, filtered, and concentrated.

The combined organic layers was washed with brine (50 mL), dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was purified by a silica gel column with 33% ethyl acetate in petroleum ether to produce 6-chloro-5-iodopyridine-2,3-diamine as a brown solid (560 mg, 97%). The mixture of 6-chloro-5-iodopyridine-2,3-diamine (100 mg, 0.37 mmol), (2,3-dichlorophenyl)boronic acid (147.3 mg, 0.77 mmol), Pd(Ph3P)4 (42.9 mg, 0.04 mmol) and sodium carbonate (118.2 mg, 1.12 mmol) in water (5 mL) and dioxane (15 mL) was heated to reflux overnight. Then the resulting solution was quenched with water (100 mL) and extracted with ethyl acetate (3×50 ml). The combined organic layers were washed with brine (50 mL), dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was purified by a silica gel column with 50% ethyl acetate in petroleum ether to produce 6-chloro-5-(2,3-dichlorophenyl)pyridine-2,3-diamine as a brown solid (80 mg, 75%). Finally, the solution of 6-chloro-5-(2,3-dichlorophenyl)pyridine-2,3-diamine (80 mg, 0.28 mmol) in trifluoroacetic acid (10 mL) and hydrochloric acid (conc., 2 mL) was heated to reflux overnight. Then the resulting mixture was quenched with water (100 mL), adjusted pH to 8 with sodium carbonate and extracted with ethyl acetate (3×80 mL). The combined organic layers was dried over anhydrous magnesium sulfate and concentrated to give a residue, which was purified by a silica gel column with 50% ethyl acetate in petroleum ether to produce 5-chloro-6-(2,3-dichlorophenyl)-2-(trifluoromethyl)-1H-imidazo[4,5-b]pyridine.
