実験手順

To an ice-cold solution of 1-butanol (5.0 g, 68 mmol) in tetrahydrofuran (15 mL) was added sodium hydride (oiliness, content 60%, 0.41 g, 17 mmol), and the mixture was stirred at room temperature for 15 minutes. After 4-chloro-3-methyl-1-(2-pyridinyl)-1H-pyrazolo[3,4-b]quinoline (1.0 g, 3.39 mmol) was added thereto at 0° C., the mixture was heated under reflux further for 1 hour. The reaction mixture was allowed to cool to room temperature, and the solvent was evaporated and concentrated under reduced pressure. Iced water was added to the residue and the mixture was neutralized with dilute hydrochloric acid, and organic matter was extracted with ethyl acetate. The extract was washed with saturated brine and water, dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue thus obtained was purified by silica gel column chromatography (ethyl acetate) to give the title compound (0.29 g, 26% yield).
