Reaction Steps

A 2 N aqueous sodium hydroxide solution (363 mL, 0.726 mmol) was added to an ethylene glycol (3.6 mL) solution of the 1-(6-{[1-(1H-imidazol-1-ylcarbonyl)piperidin-4-yl]oxy}pyrimidin-4-yl)-5-(propylsulfonyl)indoline (180 mg, 0.363 mmol) produced in Reference Example 33, and the mixture was stirred at 100° C. for 2.5 hours. To the reaction solution, water was added, followed by extraction with ethyl acetate three times. The obtained organic layer was washed with water and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to obtain the title compound as white powder (106 mg, yield: 73%).
