Procedure

3-Fluoro-4-{3-[(1S)-2-methoxy-1-methylethoxy]-5-[5-(1,3-thiazol-2-yl)-1H-pyrrol-2-yl]phenoxy}benzoic acid (84 mg, 0.179 mmol) synthesized in Example (44a) was dissolved in dichloromethane (5.0 mL), and acetohydrazide (40 mg, 0.540 mmol), HATU (200 mg, 0.526 mmol) and N,N-diisopropylethylamine (0.15 mL, 0.861 mmol) were added, followed by stirring at room temperature overnight under nitrogen atmosphere. The solvent was distilled off under reduced pressure, and the resulting residue was purified using silica gel column chromatography (elution solvent: ethyl acetate) to afford the desired compound (110 mg, yield ˜100%) as a white solid.

Workup

  1. distillationThe solvent was distilled off under reduced pressure
  2. customthe resulting residue was purified
