실험 절차

5-Hydroxy-8-methylcarbostyril (20.0 g, 0.114M) was dissolved in acetic acid (800 ml). To the solution, 10% palladium-on-carbon (10.0 g) was added. The mixture was stirred at 80° C. for 4 hours in the stream of hydrogen. The reaction mixture was filtered, and the filtrate was distilled off under reduced pressure. The residue was extracted from a mixture of chloroform-methanol (10:1) and saturated aqueous sodium bicarbonate solution. The organic phase was washed with saturated aqueous NaCl solution, dried, and condensed under reduced pressure. The resultant residue was recrystallized from methanol-ether to obtain 20.2 g of the title compound as pale yellow powdery crystals (99.9%).
