A solution of 2-(2-(1-tert-butyl-5-(4-fluorophenyl)-1H-pyrazol-4-yl)thiazol-4-yl)acetic acid (50 mg, 0.14 mmol), HATU (106 mg, 0.28 mmol), DIEA (0.049 mL, 0.28 mmol) and 4-(1H-imidazol-1-yl)benzylamine (96 mg, 0.56 mmol) in DMF (2.0 mL) was stirred at room temperature for 14 hr. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine and dried, and the solvent was evaporated under reduced pressure. The obtained residue was purified by NH-silica gel column chromatography (solvent gradient; 50→70% ethyl acetate/hexane) to give the title compound (33.4 mg, 0.065 mmol, 46.7%) as a white powder.
