According to Example 1(4), a crude product of 3-isopropyl-4-(6-methoxypyridin-3-yl)-1H-pyrazolo[3,4-b]pyridine was prepared using compound (6b) instead of compound (1c) and using 6-methoxypyridin-3-yl-boronic acid instead of quinoline-3-boronic acid and was used in the subsequent reaction without being purified. According to Example 1(5), compound (18a) (the second stage yield: 60%) was prepared using 3-isopropyl-4-(thiophen-3-yl)-1H-pyrazolo[3,4-b]pyridine instead of compound (1d).
