A solution of 3-(2′,3′-dimethyl-biphenyl-2-yl)-propionic acid (110 mg, 0.44 mmoles) and 2-(2-methoxy-ethoxy)-benzoic acid-N′-isopropyl hydrazide (100 mg, 0.40 mmoles) in DMF (3 mL) was treated with triethylamine (0.16 mL, 1.19 mmoles), HOBT (64 mg, 0.48 mmoles) and EDCI (91 mg, 0.48 mmoles) at room temperature for 48 h. The reaction mixture was partitioned between 1N HCl and ethyl acetate. The organic layer was washed successively with water, 1N NaOH and brine, then dried over sodium sulfate, filtered and concentrated. The crude was absorbed on silica and purified on a silica gel column with 10% ethyl acetate/hexanes to afford the product (70 mg, 36%). LC-MS m/e 489.39 (M+H+)
