Procedure

3-(5-Chloro-pyridin-2-yl)-5-(5-isopropyl-tetrazol-1-yl)-benzoic acid (650 mg, 1.89 mmol), C-(5-methyl-pyrazin-2-yl)-methylamine (233 mg, 1.89 mmol), EDCI (362 mg, 1.89 mmol), HOBt (255 mg, 1.89 mmol) and Et3N (1.32 mL, 9.45 mmol) were added to 10 mL methylene chloride. The reaction mixture was stirred at room temperature for 18 hours, then was partitioned between water and methylene chloride. The combined organic layers were dried (MgSO4), filtered and concentrated under reduced pressure. The resulting residue was purified via flash chromatography (80-100% EtOAc/hexanes) to give 492 mg of 3-(5-chloro-pyridin-2-yl)-5-(5-isopropyl-tetrazol-1-yl)-N-(5-methyl-pyrazin-2-ylmethyl)-benzamide, MS (M+H)=449.
