To a solution of 2-chloro-5-(5-methyl-1H-pyrazol-3-yl)-benzoic acid (100 mg, 0.422 mmol) in DMF (10 mL) was added 1-hydroxybenzotriazole (85 mg, 0.63 mmol), polystyrene supported 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (1.24 g, 1.27 mmol) and 1-aminomethyl-cycloheptanol hydrochloride (113.4 mg, 0.633 mmol). The mixture was stirred at room temperature for 15 minutes, then polystyrene supported N,N-dimethylaminopyridine (0.64 g, 0.93 mmol) was added and the mixture was stirred at room temperature for 16 h. The mixture was filtered through a glass frit, and the residue was washed thoroughly with methanol. The filtrate was concentrated to dryness in vacuo. The residue was purified by reverse phase chromatography to afford the title compound as a white solid (40 mg). LC/MS (M/z): 362.5 (M+1).
