실험 절차

A solution of (2′-ethyl-5-fluoro-biphenyl-2-yloxy)-acetic acid (38 mg, 0.1395 mmol), and 4-(2-methoxy-ethoxy)-benzoic acid-N′-isopropyl hydrazide (32 mg, 0.1268 mmol) in DMF (5 mL), was treated with triethylamine (0.053 ml, 0.38 mmol), HOBT (20 mg, 0.152 mmol), and EDCI (29 mg, 0.152 mmol) for 12 hours at room temperature. The reaction mixture was partitioned between water and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, filtered, and concentrated. The crude was absorbed on silica and purified on a silica gel column with a 50-100% ethyl acetate/hexanes gradient to afford the product as a white solid (5 mg, 7%). MS m/e 509.42 (M+H+)
