実験手順
4-(4-Amino-2-propyl-2H-pyrazolo[3,4-c]quinolin-1-yl)butan-1-ol (prepared as described in Example 593, 0.118 g, 0.396 mmol) was hydrogenated for 1.8 days using the method described in Example 59. The catalyst was removed by filtration, and the filtrate was concentrated under reduced pressure to yield an oil that was dissolved in 6 M aqueous sodium hydroxide (20 mL). The mixture was stirred for 1 day, then a white solid was isolated by filtration, washed with water, and dried at 70° C. under vacuum to provide 0.719 g of 4-(4-amino-2-propyl-6,7,8,9-tetrahydro-2H-pyrazolo[3,4-c]quinolin-1-yl)butan-1-ol as a white powder, mp 194.0-200.0° C.
