実験手順

To a solution of 1-(2-cyclopropyl-3-methyl-2H-indazol-5-yl)-4-hydroxypyridin-2(1H)-one (30 mg) in tetrahydrofuran (2 ml) were added (5-chloropyridin-2-yl)methanol (31 mg), bis(2-methoxyethyl)azodicarboxylate (55 mg) and trimethylphosphine (1 M tetrahydrofuran solution, 235 μl) at room temperature, and the mixture was stirred at the same temperature for 2 hr. The mixture was diluted with ethyl acetate, and washed with water, 1 M aqueous sodium hydroxide solution and saturated brine. The organic layer was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (NH, hexane/ethyl acetate) and recrystallized from ethyl acetate to give the title compound (22 mg).
