To a solution of 4-(2-methylthiazol-4-yl)aniline (0.05 g, 0.26 mmol) and 2,4-dichlorobenzoic acid (0.05 g, 0.26 mmol) in dimethylformamide (20 mL) and diisopropylethylamine (0.067 g, 0.09 mL, 0.52 mmol) at room temperature was added HATU (0.148 g, 0.39 mmol) in one portion. The reaction was stirred at room temperature for 4 hours, then poured in to water (200 mL) and stirred for 20 minutes. The product (0.094 g, 100%) as a light yellow solid was collected via filtration. LC-MS (M+H): 364. 1H NMR (400 MHz, dmso-d6): 10.67 (s, 1H), 7.95 (d, 2H), 7.87 (s, 1H), 7.80-7.77 (m, 3H), 7.69-7.58 (m, 2H), 2.74 (s, 3H).
