Reaction Steps

According to Example 1(6), 4-{3-isopropyl-4-(quinolin-3-yl)-1H-pyrazolo[3,4-b]pyridin-1-yl}-2-(isoxazol-3-ylamino)benzonitrile was prepared using compound (6d) instead of compound (1e) and using 3-aminoisoxazole instead of trans-aminocyclohexanol and was used in the subsequent reaction without being purified. According to Example 1(7), compound (32) (the second stage yield: 40%) was prepared as a white solid using 4-{3-isopropyl-4-(quinolin-3-yl)-1H-pyrazolo[3,4-b]pyridin-1-yl}-2-(isoxazol-3-ylamino)benzonitrile instead of compound (1f).
