実験手順
A mixture of the 5-(piperidin-3-yloxy)-1H-indazole (43 mg, 0.20 mmol) obtained in Example 377, 2-iodoethanol (84 mg, 0.49 mmol), potassium carbonate (70 mg, 0.50 mmol) and N,N-dimethylformamide (1 ml) was stirred at room temperature for 24 hours. The precipitate was removed by filtration and the solvent was distilled off as an azeotrope with toluene. The residue oil was purified by a silica gel column chromatography (eluent: ethyl acetate/triethylamine/ethanol=20/1/1) to obtain 2-[3-(1H-indazol-5-yloxy)piperidin-1-yl]ethanol (17 mg, 32%).
