Procedure

Compound (107a) (0.08 g) and iodomethane (0.16 mL) were dissolved in DMF, and sodium hydride (0.028 g, a 55% dispersion in paraffin liquid) was added to the resulting solution at 0° C., followed by stirring at room temperature for 1 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 then the solvent was distilled away to obtain 3-(dimethylamino)-4-(4-chloro-3-isopropyl-1H-pyrazolo[3,4-b]pyridin-1-yl)benzonitrile, which was used in the subsequent reaction without being purified. According to Example 107(2), compound (108) (0.014 g, the third stage yield: 12%) was prepared using 3-(dimethylamino)-4-(4-chloro-3-isopropyl-1H-pyrazolo[3,4-b]pyridin-1-yl)benzonitrile instead of compound (107a).
