PROCEDURE

实验过程

The methyl 2-(1H-indazol-5-yloxy)benzoate (95.6 g, 0.36 mmol) obtained in Example 478 was dissolved in tetrahydrofuran (5 ml), and lithium aluminum hydride (44.1 mg, 1.07 mmol) was added thereto at 0° C. and stirred for 30 minutes. Water (0.3 ml), a 2N-aqueous sodium hydroxide solution (0.6 ml) and water (0.9 ml) was added dropwise thereto in that order, and the precipitate formed was removed by filtration. A saturated aqueous sodium hydrogencarbonate solution was added to the filtrate, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, and then concentrated to obtain [2-(1H-indazol-5-yloxy)phenyl]methanol (56 mg, 65%).
