To a solution of 2-(2-(1-(tert-butoxycarbonyl)pyrrolidin-3-yloxy)phenyl)-1H-benzo[d]imidazole-4-carboxylic acid (31; 150 mg, 0.36 mmol), thiazol-2-amine (4; 35.5 mg, 0.36 mmol), and HATU (202 mg, 0.53 mmol) in DMF (5 mL) was added DIEA (137 mg, 1.06 mmol). The mixture was stirred at room temperature for 18 h. It was then diluted with water (20 mL) and stirred for 30 min. The precipitate was collected by filtration, and then purified by column chromatography to give 85 mg of the title compound 32 (yield: 48%). MS (ESI) calcd for C26H27N5O4S: 505.18; found: 506 [M+H].
