실험 절차
After dissolving 7-benzyloxy-6-cyano-4-(1H-indol-5-yloxy)quinoline (3 g, 7.6642 mmol) in tetrahydrofuran (250 ml), 10% palladium carbon powder (500 mg, wet) was added and the mixture was stirred for 11 hours at room temperature under a hydrogen atmosphere. After further adding 10% palladium carbon powder (300 mg, wet) and stirring the mixture for 9 hours at room temperature under a hydrogen atmosphere, additional 10% palladium carbon powder (200 mg, wet) was added and the mixture was stirred for 5 hours at room temperature under a hydrogen atmosphere. The solvent was distilled off, washing was performed with ethanol, and then the filtrate was distilled off under reduced pressure. The obtained crystals were suspended in ethanol and diluted with hexane, and the crystals were filtered out, washed with hexane:ethanol=3:1 and dried by aspiration to obtain the title compound (1.82 g, 6.0402 mmol, 79.12%) as light yellow crystals.
