実験手順
To a solution of 2-(2-aminoethyl)-4,6-bis(4-fluorophenyl)-5-(4-pyridyl)pyrazolo[3,4-b]pyridine (0.06 g, 0.15 mmol, obtained in example 90) and DMAP (0.001 g, 0.0058 mmol) in pyridine (0.6 mL), methanesulfonyl chloride (0.017 mL, 0.22 mmol) was added under argon atmosphere and cooled with an ice bath (0.017 mL, 0.22 mmol). This was stirred overnight at room temperature. The solvent was concentrated. The residue was dissolved in CHCl3 and saturated NaHCO3 was added. The phases were separated. The organic phase was dried over Na2SO4 and concentrated. The crude product obtained was purified by chromatography on silica gel using EtOAc as solvent, and 70 mg of the title compound was obtained (yield: 95%).
