반응 단계
Isoorotic acid (0.021 g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.029 g), and 1-hydroxybenzotriazole monohydrate (0.016 g) were added to a solution of compound (77a) (0.050 g) in DMF (1.0 mL), followed by stirring under argon flow at room temperature for 15 hr. The reaction solution was distributed between ethyl acetate and water, and the organic layer was washed with saturated saline. The organic layer after the washing was dried over anhydrous sodium sulfate, and the solvent was distilled away to obtain 2-{1-(2,6-dihydroxypyrimidine-4-carbonyl)piperidin-4-ylamino}-4-{3-isopropyl-4-(quinolin-3-yl)-1H-pyrazolo[3,4-b]pyridin-1-yl}benzonitrile, which was used in the subsequent reaction without being purified. According to Example 1(7), compound (78) (0.026 g, the second stage yield: 39%) was prepared as a white solid using 2-{1-(2,6-dihydroxypyrimidine-4-carbonyl)piperidin-4-ylamino}-4-{3-isopropyl-4-(quinolin-3-yl)-1H-pyrazolo[3,4-b]pyridin-1-yl}benzonitrile instead of compound (1f).
