Procedure
To a solution of 4-[5-chloro-2-(chloromethyl)-1H-benzimidazol-1-yl]-1-(4-methoxybenzyl)pyrrolidin-2-one (294 mg, 1.492 mmol) in 50 mL of DMF was added 3-(methylsulfonyl)-1H-pyrazolo[3,4-c]pyridine (722 mg, 1.791 mmol) and Cs2CO3 (584 mg, 2.985 mmol). The resulting mixture was stirred at RT for 4 hours, then diluted with 40 mL of H2O and EtOAc. The separated aqueous phase was extracted with EtOAc (15 mL×3). The combined organic phases were washed with 30 mL of brine, and then dried over Na2SO4, then filtered and concentrated in vacuo. The residue was purified by column chromatography (DCM: MeOH=20:1) to give 4-(5-chloro-2-{[3-(methylsulfonyl)-1H-pyrazolo[3,4-c]pyridin-1-yl]methyl}-1H-benzimidazol-1-yl)-1-(4-methoxybenzyl)pyrrolidin-2-one as a solid.
