실험 절차

After adding 6.0 mg (0.16 mmol) of lithium aluminum hydride to a solution of 60.0 mg (0.15 mmol) of the 6-[3-isopropoxy-5-(thiazol-2-ylcarbamoyl)-phenoxy]-nicotinic acid methyl ester obtained in Production Example 65 in tetrahydrofuran (5.0 ml) while cooling on ice, the mixture was stirred at 0° C. for 1 hour. Saturated aqueous sodium hydrogencarbonate was added to the reaction mixture, extraction was performed with ethyl acetate, and the organic layer was dried and then concentrated under reduced pressure. The obtained residue was purified by silica gel chromatography (chloroform:methanol=30:1) to obtain the title compound as a white solid. The analysis data for the compound obtained in Production Example 66 are shown below.
