A mixture of 2-chloro-5-(2-methyl-thiazol-4-yl)-benzoic acid (7 mg, 0.027 mmol), 1-aminomethyl-cycloheptanol (6 mg, 0.03 mmol), 1-hydroxybenzotriazole (5 mg, 0.03 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (6 mg, 0.03 mmol) and triethylamine (5 μL, 0.03 mmol) in N,N-dimethylformamide (0.5 mL) was stirred at room temperature for 16 h. The mixture was diluted with ethyl acetate and washed with 5% citric acid, water, then brine. The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by column chromatography (1:1 ethyl acetate-hexanes) to afford the title compound (3.4 mg).
