Procedure

N′-Acetyl-5-{3-[4-(azetidin-1-ylcarbonyl)-2-fluorophenoxy]-5-[(1S)-2-methoxy-1-methylethoxy]phenyl}-1H-pyrrole-2-carbohydrazide (86 mg, 0.16 mmol) synthesized in Example (66h) was dissolved in dichloromethane (5 mL), and triethylamine (0.1 mL, 0.72 mmol) and p-toluenesulfonic acid chloride (69 mg, 0.36 mmol) were added, followed by stirring at room temperature overnight. The reaction solution was diluted with dichloromethane (60 mL), washed with 1N hydrochloric acid, a saturated aqueous sodium hydrogencarbonate solution and saturated brine, and subsequently dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the resulting residue was purified using silica gel column chromatography (elution solvent: ethyl acetate/hexane=50%-100%) to afford the desired product (57 mg, yield 69%) as a white solid.
